Sops reveal many features of galaxies and the features reveal structure patterns common to various types of objects.


Enlarge -141y.

AHZ200141y 0.231000 {.140 G z.569} sop1 purple flanks, orange tips, one with yellow flecks and the other with a tangential curve blue inverted flare or unsegmented train. Sop2 reveals more orange stroking around the target core with a green stroke inside the flare feature. The companion has 3 teal nodes and a broad 1bjd object and nodes stroke. AHZ2000gim insert.

AHZ2000cs0 flare features of 141y above
AHZ2000cs0 1gb8 fill features
AHZ2000cs0 curve features

Another curve 1bjd stroke field companion feature near 164u whose target has sop3 in green sop2 nest.
These objects combine aspects of interactive systems and strongly lensed features.

Examples of 1bjd stroked, 'trained' systems ...
AHZ20010x3 accent-poster with 1bjd strokes AND AHZ20010x3 3 sop2 strokes
AHZ20003po cleanly stroked 'comma' AND AHZ20003po curve view
AHZ20011dk 'pair' with weak 0txd-like train
AHZ2001iqh ibjd target above field companion and poster, p9, SDSS insert
AHZc001o79_sop and AHZc001o79_bw asymmetrical pseudo-ring system with train. The field has a lensed object.

AHZ2001kdq_sop and AHZ2001kdq_bw

These objects make for an interesting clutch of thematic steps of hypothetical progression when a galactic system dynamically changes forms.



The first 2 objects AHZ2000y5n and AHZ2000y9b have their objects rendered with curve to amplify the G features.
They both have asymmetries about a sop3 core and 1bjd filled trains extending out around their perimeter.

Another on AHZ2001g4o has the sop3 and adjacent sop2_y like -0y9b above but not -0y5n.

Although not thematically in this thread the use of sop stroking may be useful
for identifying lenticular and elliptical objects.
This object was posted in the 'overlapping' thread.
This is AHZ2000ztj which may be an elliptical with a lensed object.

AHZ20011zf another G_lens but not referenced by NED.

This is AHZ2000c28 and it is referenced as a lens or lens candidate.
Let's call it a GALACTIC SYSTEM (in a 2D field) until we can read the article. There does appear to be 2 objects.

In the last image the poster2 inset and the sop1 and sop2 strokes look more like 2 proximal objects.
The target is neither an elliptical nor a lenticular.

AHZ200106d looks like another lensing elliptical ...

and the 'black & white'  brings up the possibility that 2 objects might be lensed. The objects below the target are both sop1-y stroked and sop2-g filled.

AHZ20015i3 is posted in the 'lenticular' thread ...

It is impressionable as a lenticular and it also has a very strongly lensed object at the top with 2 telltale sop stroke and fill patterns.
Evidence for elliptical, rather than lenticular, are the sop1 stroke bands and broad poster 2 core along with the satellite feature - like in the sop1 exemplar.

For a change his is an Aegis image of AHZ1000564.
(NGC 7525 / Mrk 316 / SDSS J231340.49+140115.5 Sy1 1237656495108718727, 1237656495108718728 - formation prospect?)

NED reports objects and different z-values and that one or more is an IrS.
The images do reflect the poster 2 core feature that points to an elliptical object but the Aegis rendition is not that compatible with the sop stroking.
The satellite feature has 1bjd 'beads' and compact sop2 fills. The companion doesn't look like a lensed object.
The most obvious feature is the amount of sop3 stroking in both objects. It looks like a sop3 core was shredded - mechanism for lenticular formation?

This is AHZ20017wo.

It has a lens (candidate?) reference in NED but maybe that stuff in the red object near the other object might be something else.
If it is not a product of the red object maybe it arose by an interaction with the companion object?
The image on the right is has a poster 2 feature contribution and the left image has a curve core inserted in the top object.

“It seems that really active black holes are rare but not antisocial,” said Haggard.
“This has been a surprise to some, but might provide important clues about how the
environment affects black hole growth.”
- AGN ref titled "Will the Milky Way’s Black Hole Become ‘Hyperactive’?"



Put http://www.galaxyzoo.org/examine/AHZ20016cz in here.
The 16cz_sop and 16cz_bw images provide evidence that the target is a ring/polar ring transition.

More comparisons of elliptical and lenticular objects.

A rather alien look imparted in PS to an object recently posted in the newbie thread.
Quote
Rather prefer the rounder, close object at 7:30 - 8 in the AHZ2000h0z field,
from the newbie thread, and not all that strong. The spindly object at 11 may
be an even better choice. Let's hope we get a another, better image of
the LRG and field.
The reply demonstrates how fast an image can take on different features. The 7:30 feature
was found to have a 1bjd fill as indicated however the 11:00 feature remains stroked with lens-sops.
Coincidentally, there is another post with -0ehj mentioned as a lenticular and -0h0z is compared with it.

NED mentions a GCluster at z.3 (in front of and/or centered?) near -0h0z and there are several other
targets with references by Faure.



A 2007 reference popped up in NED that is on topic and may shed further light on this issue of clarifying object types.
Quote
There is a Moran reference with objects near this Ra/Dec and it IDs 3 objects (F1/F2/F11) as ellipticals and an S0 respectively.
Few here would classify the presumptive target, AHZ300003k, in this field to be an elliptical.



Classification object, AHZ60005rr, with an anemic spectra but a healthy H-alpha signature -
587730847424905242, aka 8647474691925148204 z.186.

The previous reply holds presumptive elliptical objects and this one may have lenticulars for comparison.

This first one, AHZ20001jm, is from the edge-on galaxy thread and discussed as a possible ring galaxy.
The target has sop1 green and blue core strokes that are 'clean' at this angle in what appears to be a dusty field.
The poster 2 view is complex and perhaps affected by obscuring material.
The Spitzer quote may help to explain the complexity. The sop3 fill and stroke features are interesting too like AHZ20012qk .


Quote
"...24 μm data are biased toward warm AGNs and are affected by broad mid-infrared PAH
emission and silicate absorption features redshifted into the band."
- D.T.Frayer, etal., 2009



Ink's not dry here and another report comes along hot off the press.
Galaxy Halos Recycle Interstellar Gas Into Baby Stars is about 3 papers being published in Science which
study the location of these halos, and how gas moves into and out of galaxies.




From the 'merger' file, AHZ200190g complements -01jm and may help resolve red objects with blue tips. (The classification target is arbitrarily ambiguous.) The larger and closer(?) blue object and cigar red object have many exemplar strokes. The b&w boundary image shows the red object with a curve fill. Sop3 fill features are located at the ends of the cigar. Sop1_y and sop2_1bjd strokes are sparce closely layered at the margin of the blue object - the ambiguous target area. 

There was a recent post with a reference by Comerford regarding 2x and 3x AGN systems and after viewing -190g it is not hard to imagine that this system may be capable of displaying 2x AGNs.

Continuation of reply 15:

AHZ20014so is one of the more interesting examples of 'limb flow' or training. It was posted in the 'merge' thread perhaps due to the editing done on the image which made it bluer. The eye gravitates to the core and the starburst foci.

There are easy sop2 strokes which indicate sop3 features and further fuel the suspicion that the target is busy. NED has it as a RadioS.
This core interaction will have to wait for further elaboration. The feature which is prominent however is the sop1 marked arms wrapping around the target. Notably, the 1bjd 'flare' (a fortunate sop2 fill that has a distant fleck at the far left) seems to bubble out of the object along with sop1_y. (There is a yellow fleck under the 1bjd fleck.) Although an anemic train system, it does underscore the ambiguous/sporatic core activity. Note the sop3 core flecks overlaying the poster 2 and curve inlay.

AHZ2000cig b&w and -0cig_sop extend the observation of -14so.


This is a similar object AHZ2001hig for comparision.

It is redder and in traffic. The activity in the system seems to be focused around the companion object rather than on the adjacent 1bjd feature.
Three stroked objects around the target look like a lensed object.



That 'rose thorn' sop2_1bjd fill from -14so, above, and the leftmost fleck(s) are striking efferent features.
This object, AHZ2001jfe, also has similar features. (note: The zs are all over the place and an object in the field may
be a RadioS.) Classified as having a lensed feature, that estimate seems very unlikely now - btw, the actual lens need
not be the target.

This group of images, and the few with inserts, might be a more interesting view after reading this piece about humongous BHs.

AHZ2000cpo was classified as a merger after reading the recent GZ blog about redder and bluer objects
mingling and then entering a presumptive AGN phase. (It was posted in June in the merger thread.) Unfortunately NED was no help.
(Approximate Ra & Dec for -2000cpo @ http://cas.sdss.org/dr6/en/tools/explore/obj.asp?id=587726032235463488)

If these two images were available the classification might have been different. The target seems estranged from the field companion and a bit ragtag.
Both objects look quiet although one might argue that the curve target may be percolating in the right arm. In the b&w image the Sop3 core overlap fill
seems really anemic relative to the blue poster 2 feature. Perhaps a failed merger and someone forgot to turn on/off an AGN?

The third field is AHZ2001mbh. It has an SDSS insert of an object to the S. It was included here to show a similar formation and what looks like a detached limb. This is the 1mbh_sop view.


AHZ20000hh4 was included, as chance would have it, inset with another SDSS field object. The type-1 AGN sop3_fill and stroke are distributed in the target
and a field companion. (Mention in the summary about the sop3 features being distributed adjacent, apart and singularly.)



AHZ2001e34 isn't much to look at. It might pass for a fake at first glance.
The combined sop image has a curve core overlay to emphasize the compact nature of the target.
The b&w has the poster 2 core overlay.

A sop3_164u_15 torus was not included over the core - it covers roughly the blue torus of the curve inset.
(The BEL classification agrees with the type1 Seyfert sop3 fill.) The target is swathed thinly in sop2_1bjd_10.

This is an extra post for temporary notes.

A sop is a Set Of Pixels.
Sop1 started from an image with a system with 2 red core features and wispy blue 'clouds' in the foreground.
The sops were elaborated further from several other objects with other blue features. The hope was to view
an object from other angles and be able to identify features that shared sop types.
After some trial and error 3 sops were made.
Optimal assignment of color and other PS/app features to accentuate object/target structures.

Combining sop elements like sop1_y(a yellow stroke) and sop2_g(a green fill or stroke) over a galaxy system feature
like a suspected lensed object was promising. (Maybe identify lensed objects and find an unknown lens?)
Another pair of sop elements was used to reveal patterns over a black background and white field objects with and without
poster 2 and sop3 features. The poster and core-related fills and strokes also serve as placement markers among
several images.
The sop3 set may be Seyfert type1 and type2 core features.
These objects don't always have ample NED or other data available to elaborate interpretations.
Attempts are made to explain the Photoshop features used in the images like curve, poster 2, fill and stroke.

It is also hoped that more useful images can be provided that enable more accurate classification of objects.
Adobe might be persuaded to avail the Zoo an app for general use. (A new version of PS is quite expensive.)



There appear to be many objects which have sop3 features outside the 'center' of targets. It does not look like the
putative ansae features are passive structures. It might be worthwhile to look into how the objects are spectrally
identified and what feature(s) is/are interpreted.

The group/class of objects (in other notes) also are mentioned with other 'active' field object(s.)

Continuation of reply 16. Lensed objects?
and S-shaped AGNs


-0n7o_bw is a NED GLens. A reference with it, Lagattuta et al., 2010, has all 40 GLens IDs.
There is an interesting pair of flanking sop2_o and sop2_g feature noted with an asterisk.
A larger image of -0n7o_sop. This target resembles the original sop exemplar.



This is (an elliptical?) AHZ2000fpo. It is a type 2 AGN and has the peri-nuclear sop3_fill juxtaposed with the sop1_fills green and blue.



This is the AHZ20019bc field with a large off-field object and a field companion and both have type2 AGN sop2_fill features.
(-04or_sop should nicely complement this image's larger field companion and -04or_bw. The SDSS insert shows the position
of the RadioS in the -04or image.)
-074r_sop and -074r_bw (NED Gpair?) resemble the RadioS in the -04or field. The images don't include another RadioS
 - lower left - inset.



AHZ2000i8r_sop (-0i8r_bw) has a train and it passes over a field companion at z.8. The companion, a Sy2, is -0i8q.
This shape of -0i8r echos the shape of -19bc's poster feature. The insert has the 2 satellites viewed from that target.

Fields containing both Sy1 and Sy2 (sop3)



-0rfh was posted due to the 'accordion' feature stretched across the top of the target. It is as if a SBa or SBb layered into
2 systems with one expanding and carrying Sy1 parts and the other a Sy2 core. The target is near a 3-field seam but it mostly
resides in the lower right field. The inset shows several XraySs and a RadioS field companions in the area.

Here are more examples of 'layered' systems - DR8 1237680299428806739 and DR8 1237648721784078676.
AHZ6000alp might qualify as a 'symbiotic' layered GTriple system (DR6 588015510348759173.)

As viewed in another reply (reply 9,) geologists also notice a pattern in large scale structures in the Earth.
"
Together, the two dipping segments give the fault a shape that resembles a propeller.
Why the earth contorted itself into this geometry is still unclear. Fuis and his team think
the propeller shape may make it easier for the Pacific and North American plates to slide
past each other, ...
" - Fuis


-1dny_sop has Sy1Sy2 companions.
The 'pair' at the lower right has a shared sop2_yellow/sop3_Sy2 core AND a 1bjd nested Sy1.
The inset shows the target in the square box with flanking Radio and Xray Sources.
The actual target in -1dny looks like the 1bjd companion.
(When I see these smallish targets and companions I get the feeling they might be flung objects.
The larger objects also seem to be losing bulk - their symmetries are often very lopsided. Some
companions are like layers shed from a bulkier object.)
-1dny_bw shows the Sy2 companion without the sop2_yellow core.
I keep the, sunken, sop1_yellow in the Target_bw images to look for lensed objects. The dark blue
flecks are poster 2 features. The red marking is a sop3 stroke to accent it when several sop overlap - it is not
an elliptical-like poster 2 red.


-057a_sop is also a Sy1/Sy2 field.
The target in this case is a bulkier item. The assumed core
has the Sy2 (b&e) fill BUT the sop2_yellow (Sy2 marker)
is an 'ansal' feature. The really interesting object is the half-
rendered, bottom left item. Like the companion object above
it has a toroidal sop3_Sy1. The Hubble NED link tagged this
companion as the target - as a star!
The insert shows the Radio and Xray Sources in the field.

-057a_bw doesn't afford much more viewing.
(At the top, the sop2_yellow b&e-fill was x-marked from the
sop3 fill stroke.) The Sy2 core fill was stroked to distinguish it
from the Sy1 toroid off to the right. I think that is a quasar
(and it would be a very interesting find.)


-0rj2 could pass for a twin of -057a.
<--------


A recent newbie post has an interesting dynamical appearance.

The target has Sy2 fragments trailing toward the QSO with the Sy1 core.
This field has little more NED information.
Here are curve and b&w renderings.

Continuation of reply23 ...

This system has a lens reference and is an IrS. The lens(ing) reference raises the specter from another reply (of an unidentified target) that the image was faked or that the lensed features might be blended with another object. In deference to this field, the features appear to be cogent enough to state that the target is a single complex system. (The sopped strokes don't indicate an unambiguous lensed feature in the target.)
Ironically, the complexity of the system arises from the fact that it is in a relatively 'clear' field and lacks volatile neighbors save for a XrayS(*?) and RadioSG.
The targets in reply23 are multi-object systems containing Sy1 and Sy2 features. This target has them in one object or one very compact 2-D place. The Twins come to mind when viewing this target. There is also a training semblance (a Kelvin-Helmholtz instability?) with the Sy1 features.
Lastly, the name is also ironic -0bot! The black&white image shows a botish face.
 
The left image shows the roundish Sy1 (core) and red-stroked (near core) features near a thrice-stroked target core.  The right image is a curve overlay of the system. The view might also represent a Sy1 formation in front of a Sy2 2-arm backdrop - or a mutated bar system? Compare with AHZ20000fk.

A quotation from Z's reference draft about 2 AGN systems.
"UNDERSTANDING DUAL AGN ACTIVATION IN THE NEARBY UNIVERSE"
"
This type of extensive study is impossible to do at
higher redshifts because of surface brightness dimming
and the limitations in resolution and exposure time, par-
ticularly in X-rays since the secondary AGN are typically
10-100x fainter. However, the pair fraction and frequency
of gas-rich ”wet” galaxy mergers increases with redshift.
This suggests that dual AGN activation may be much
more common at higher redshifts.

Three similar-z-GSs with a focus on environmental variations. These are probably all barred systems.
We had a Zoo-featured paper about the possible demise of systems with a bar feature.
Perhaps it is not too far fetched to imagine that the systems here won't become QSO systems.
However as for demise, well maybe the term recycled might be more appropriate.

Larger images:
AHZ2001gyj
AHZ2000oyl
AHZ2000hhf
These images are displayed with poster 2 (red with a shadow) core zones to accent the Sy2 nodes
in the systems. 2 images are scaled the same and the third is zoomed out somewhat.
There is also a sop1 blue stroke and fill to add to the mix. The center image is devoid of nuclear Sy features
and it with the system on the right have detached 'core's or ansae off a training limb.
It would be fantastic to find an entire sequence of these events.

AHZ20000fk
AHZ300003k
AHZ200001z
As with the other 3 the accent is on the internal distribution of features. These are at z~.4 and the others are at z~.6.
The flanking systems are again barred objects. The center system is part of a paired dynamic. These have an orange
sop1 stroke about each 'core.' The left system is quite busy in its periphery despite a composed nuclear area. Any 'core'
training seems to be to the dominant ansa and there is a streaky (AGN-like) flare off to the left. The limbs are not overly
extended and a small satellite is off the end of the flare.
The center object has 2 ostensible satellites and a -0hhf-like 'core.' The paired system seems to be similarly disposed to
a 'leaky' environment. The right system has an 'eye' on things! The 'eye' is an unusual inset curve rendition and it does
show a rather substantial nuclear region with an 'evicted' Sy2 formation. The training appears to be toward the lesser ansa.
Note the orange 'core' strokes of the left and right images.
The flared feature of -00fk bears further monitoring and comparison with similar targets.

Any mention of formations or movement in these systems herein is purely implied. The value of using sops(color) to denote
or paint galactic system regions via pixel content may be coincidental.

For the sake of actually having a QSO these two fit the bill.  They share many attributes including scale and appearance.
Based on previous sop observations the target on the right may also be lensing - but NED has no lens reference.

There are two objects (same Ra,Dec) characterized in Cowie1. These objects are shown with very different z-values but their
'true' values are closer than the cited AHZ-reference values. It is very gratifying to have a scientifically identified object and sop
stroke in agreement. The objects differ with various sop strokes and that may reflect their variability and/or intrinsic compositions. 
They, and others, should provide more exemplars for vigorously classified 'compact' objects with sopped features.

AHZ2000cih_sop exemplifies the difficulty tracking objects. Although the field companion (target) is compact and stroked as a Sy2 and
adjacent to a partial system with a Sy2 also, the relationship is very sketchy. The poster 2 sequence is overlaid from the blue target to
the bisected core. The poster colors vary in the target and partial companion and that may be useful when comparing other examples.
Reply 18 has AHZ200190g as a system with similar features.

Here is a recent quote from Space.com.
"compiled a catalogue of 23,000 quasars observed by the Sloan Digital Sky Survey"
"They ended up with three cases, which they report in a paper published recently in the journal Astronomy and Astrophysics.
There are also more candidates that the scientists hope to confirm with future observations."
"there are no other known cases of quasar host galaxies lensing background galaxies"

Yes, we have many questions; do you have many ansae? These targets are interesting beyond their complx anatomies.
When viewing flat, and presumably spiral, disc-like objects do we tend to bias a classification?
They are the same scale and their z-values aren't that dissimilar.

3 views of AHZ2000d0x to observe the ansae with other targets. (Also posted in forum.)
The target is a XrayS and (possible - NED) S2b - reference1. It has a z.2 QSO and another XrayS in its field.
The 2-bar-system is explained in the reference. These images explore sop2 and sop1 stroke affinities.
The 'raised' nuclear 'button' and flanking red 'ribbon' and green ansae are from the poster 2 app.
These ansar formations are echoed in the comparison of AHZ2000cig and AHZ20014so in Reply 19.



2 views of AHZ2001kxm. A barred system with a poster 3 fill contributing to the blue raised tips and central core.
Is there and inclination and attraction to field companion IrSs?


2 views of AHZ20017dl. Accented with poster 2 and poster 4 features there are again suggestions that the system
is lacking symmetry and perhaps 'drawn' to or 'depleted' by a field companion - see inset.

1Lisker et al., 2006




-0n7t is the sop of this target and unidentified companion.
The edgewise companion is not like the barred targets in this reply. It might be a lenticular and
seems to have a dust lane. The sop strokes accentuate the asymmetry of the companion. The
poster 2 inlay shows a linear feature with superimposed Sy2 segments.

While viewing an area around a dim target this scene was found.

There appears to be 3 3-D companion systems. A small on-edge
system lies between the companions. With some patience, a
few fills and strokes were done to reveal a MO/HV-like feature
and a compact object near the feature. The compact system
did not appear to be an examined object. The Sy1 fill was
stroked red and moved to expose the other strokes at the
same small area. There are many IrSs at ~z.3 in the field inset
and a large XrayS.
The companion looks like a mature z.4 MO/HV in this configuration.
(B&W view of AHZ10002o3.)

AHZ2001p4u is another HV/MO candidate.

AHZ2000fea is too big and busy not to take a closer look at.

It has an interesting projection, or conjunction, along a poster 2
limb  and it may be analogous to -02o3's compact companion
feature. The internal contour rendering was done with a curve.
The companion at the bottom has a Sy1-skirt core feature and
there is another skirt above the Sy2 target core.

(The mauve-ish fill is purely coincidental and not related to other
'mauve' posts.)

-0fea_bw


And with yet more imagination, here are 2 views of
-00c1 provided from 2 targets.
The inset has a closer view of a field companion. Are
the conditions right to produce this presumptive Z>1?

This one doesn't require imagination. It is documented at >z1.0 and z.4. These are the sop and this is the b&w versions of -0rfy.
There are insets with -0rfy. The boxed images are curves and the bevel is the scaled field with few field companions.
NED has many references about -0rfy and the references have newer, 2012, citations.
Most citations address the relation of AGN to various systems and red shift.

A continuation of reply 29 with regard to -0fea.

-1slq was mentioned as a reply in the 'irregular' thread.
Without these extra enhancements, there is only
so far that a cursory examination might go. The
discussion in Reply #5483 on: March 22, 2012 was
predicated on this image. This is the b&w link of -1slq.

There have been a few of these 'twist tie' systems
and the 'thread' of similarity lies in the hairpin feature
which seems to extend out from the plane of the system.
This brings us to the topic of extraneous limbs and 'islands.'

In reply 20 'training' features were discussed. Here we
notice similar 'phased' or grouped structures extending out
from the main body of a system. -0u2f depicts a
thematic train of 'fragments' seemingly flowing from the arm
into planet-like orbits. It would be very interesting if the
fragments were formed at intervals

With -0u4r we go -0u2f one better by placing a Sy1 node
into the 'planetary' mix. Only a limited view of the 'parent'
system is available.

AHZ2001oku, also without a scale, is rendered with a stroke rather than a fill to offer an alternative viewing of another
-1slq-like system. The larger, 'active' bulk of the systems are similar as is the relative ratio of the two parts. It would
be great to get a solid redshift for either of these targets or companions.



-07uv, like -0cih, looks more like 2 independent systems.
In this rendering white lines are 'skewers' to fix the positions
of the fills and strokes to the larger -07ux companion. This
subject of discordant Z-values came up before. Think of the
variation of the z as being dependent upon its 'local'
environment.

Sy1s are notorious for 'altered' z-values. The system or
systems can be much closer that the z dictates they should
be. The converse could also be true - if their zs are the same
then the contributors may not be close to each other. Read
the link in reply 31 for system 'pairing' parameters.

The skewered companion has a truncated line pointing to the
-07uv system core. The other sop colors are teased out and
fixed on that same 'axis' line.

The inset shows the other target -07ux.
