It's a quasar! http://en.wikipedia.org/wiki/Quasar Classify them as "Star/Don't Know", but take a moment to admire because they are *way* cool. Here's some more introductory info:

Enigma Variations: Z-scapes to Ponder
« Reply #4 on: November 08, 2009, 08:16:44 pm »
A series of 'annotated' images designed to show what may or may not be or contribute to QSOs.
The replies started before Hubble images were available and were rendered to emphasize pixel
'personalities' of various systems.

Why Enigma Variations, it's a simple and very complex question. With all due respect to Elgar, from whom the musical title is derived, the term immediately invokes a problem with many solutions, or vice versa? These EV all implore us to ask how such objects coexist, not unto themselves, but in consort as they appear. Perhaps the birth and life of QSOs will be better understood from collective EV observation. Like AGN the EV come across as oddities but that may only be a temporal interpretation. Most if not all galaxies have facets that are 'alive' with activities the humble astronomer pines to recognize and understand. Here are seven EV for our consideration at GZ.
(Besides, Exotic Vehicles sounds like a classic car list and Extreme Velocity is too trendy not to mention misleading.)

12/09/09 update "Astronomers think ... a cosmic phenomenon called quasars ... occur when mass pours onto huge black holes,
and some material is flung away in bright jets of high-energy radiation that can be seen across the universe. "

- http://news.yahoo.com/s/space/20091208/sc_space/monsterblackholesmaygrowingiantstarcocoons
http://en.wikipedia.org/wiki/List_of_quasars

5877353480279819211 has no NED notes or references and is classified as "galaxy." Coupled with an adjacent blue object it might pass for an asteroid - there is a small asteroid nearby. UGC 05832 seems to possess this red object at the end of an anemic arm. This object was chosen as an Enigma Variation due to its z .202 and the large blue galaxy juxtaposed at z .004.
(There is also another feature over the galaxy out of view, 587735348027982088 z .067, mirroring the 'eye' of UGC 08489 below.)

1Romano et al., 2008. (Arp 291, UGC5832, VV112)

587729158428950547 is classified in NED as UvES. Its z .775 contrasts sharply with the surrounding NGC 4765 z .002. It has one 'quasar' reference. Like UGC 05832 above it is a blue galaxy but without obvious arms. The location of this Enigma Variation is straddling one of the nuclear domains. (For additional background on QSO theory Google 'Halton Arp.')


587735348571996236 aka MRK 0750 is a QSO z .002. This EV is odd because of the reciprocal relationship of the object and a 'nearby' galaxy at z .130. (Usually the objects have high z and the galaxies have low z values.) It seems to be the 'nature' of the EV to 1) bring 2 different objects in proximity and 2) arbitrarily mark the objects at very different z values. In this case the QSO is blue and the galaxy is white. The QSO also has arm-like, rotational features.


588017114513014879 has a z .1 and galaxy UGC 08489 is z .04. This EV is framed in blue like others in this series. At the end of the prominent galaxy arm this "galaxy" object looks like a remote sensing 'eye.' This object might be interacting with the arm rather than a part of the arm. It also seems to be leaving the galaxy.


588015509291532489 z .265 and UGC 02705 z .022 resemble aspects of two other EV(EV1 and EV4) in this series. There also appears to be a less lopsided volumetric aspect ratio between these two objects.


587733441590198288 QSO z .231 is embedded in NGC 6185 z .034. The elliptical galaxy doesn't readily show its features and, at first glance, the QSO is easily visually hidden.


588017947199078473 QSO z 2.183 is appearing lensed by a z .075 galaxy (group) and a timid RadioS, object origin, at the adjacent galaxy fringe. Visually this QSO looms as large as many objects in our galaxy. It gives one pause to reflect upon what a lensed Milky Way might look like from that QSO!


588848900434427973, aka EV8, z .115 lies along a sweeping arc(blue overlay) of objects(red stroke) in NGC 2967 z .006. Another band(green overlay) of objects lie outside the galaxy core. The overlays are like Hadron's acceleration pathways. This grouping is a really elegant display of these objects. The QSO pixels were used to find matching objects which were stroked red. Overlays were added to 'connect the dots.'


587731186736300076 z .394 and another object z .245 are 'possessions' of NGC 7603 z .029. This menagerie is amazing even though there are many other galaxies possessing numerous EV yet to be characterized. It is amazing because the objects are splayed in a dynamic 2-D array and ripe for observation without extraneous clutter. One can't help but machinate an environment that can produce such a spatial result. Btw, that pendular object hanging at the left terminus is z .057.


These 2 references are from NGC 3338 NED data. This z .004 galaxy, 587735348564787262, has 2 QSO z > 2.

"Any supersymmetric particles, on the other hand, will decay in as little as 10-16 seconds into a slew of secondary particles, culminating in a cascade of neutralinos. Because neutralinos barely interact with other particles, they will evade the LHC's detectors. Paradoxically, this may make them relatively easy to find as the energy and momentum they carry will appear to be missing. This, in principle, is something quite distinctive. If supersymmetry does smooth the way for string theory, however, that could be a decisive step towards a theory that solves the greatest unsolved problem of physics: why gravity seems so different to all the rest of the forces in nature. If so, supersymmetry really could have all the answers."

Semantic cans of worms and obsolescent diaspora - QSOs or ?SOs

Semantic cans of worms and obsolescent diaspora - QSOs or ?SOs

Update 02/05/2010 - Chandra released an X-ray image of two QSO (587732769986641971) at
http://chandra.harvard.edu/photo/2010/sdss/ and they add that (proximal) twins are quite rare.


( Not many visitors to the Zoo are unaware of the cosmic dynamics ascribed to Dark Matter. About 75% of this galaxy
is not the stuff of we and that's a lot of stuff. We are very grateful for the gravitational attribute of that
stuff. Now let's consider what the 25%/75% unknown ratio might imply. If a man goes into a kitchen to boil an egg
and there was a 75% chance he will leave the room on a plate carried by an egg would he skip breakfast? )

Enter the Twins.


QSO 0957+561, 587729388218679312, is/are an EV of long-standing observation. It may be a (qualified)lensed QSO or
it could be twins. There is conjecture whether a singe lensed object in this 'position' can appear this way. On
the other hand, they could appear this way if one assumed they were accompanied by a MECO but not a Black Hole.
Both descriptions have odds of being accurate. There may be other explanations as well.

The latter concept entertaining a MECO structure opens the door to our hypothetical kitchen mentioned above. Unlike
Black Holes MECOs may reliably transfer 'information.' (The egg is on the plate when the man leaves the kitchen.)
This idiosyncrasy of MECOs might even allow information retrieval, something that Black Holes may or may not do.
It was observed that information from one twin(A) also came from the other twin(B) over a year later.
(If FIFO info then A before B, else LIFO then B before A.) "While many models of quasars based on
black holes exist in the literature, none of them are able to account for all four of the components of the internal
structure observed within Q0957."* This object was also the topic of a microlensed extrasolar planet.

Looking at the object(s) gives one pause to imagine this object (?SO EV) wandering away from an early Milky Way
and later releasing an ancient picture of the this neighborhood 8 billion years ago for us to wonder about.

Moreover it would be even more exciting to take a quantum peek at tomorrow.

May, 2011 update: Universe's Not-So-Missing Mass
Quote
X-ray observations provide important information about physical properties of large-scale structures, which can help astrophysicists better understand their true nature. Until now, they had been making deductions based only on numerical models, so the discovery is a huge step forward in determining what amount of mass is actually contained within filaments.

Dynamic illustrations with ?SOs

EV

It took a while to make these compisited images and in some small way might provide a visual metaphor of EV dynamics. The objects are from SDSS and the 'in situ' image pixels are not altered. Photoshop was used to transform image pixels, via software tools, directly into abstracted secondary images without extraneous overlays 'into' any image. The only layers added to the image are stroked pixel 'maps' of shared content from in situ images.



The first objects, 587741727124553845, are z .06 galaxies that hint AGN. (After viewing enough galaxies in the Zoo one wonders whether it is possible NOT to entertain the association of AGN and BH with every galaxy.) At first glance the objects are diffuse objects with bright bulges. There are faint symmetrical tinges of blue in the larger object on the right. The objects are also 'flat,' like fried eggs,  for maximum viewing of their structures. The lower left object has spectral data. The first contour map overlay delineates similar, in situ, zones in both objects and an extra core 'shadow,' also yellow, over the blue tinged region. There is an isolated, small, circular object below the shadow.

In the second image of the series the contour map remains but the objects have been posterized, or 'abstracted,' with Photoshop. The abstract layer thus contains a kind of pixel 'density map' of the two objects. The smaller galaxy, from the in situ layer, looks larger in the abstracted layer due to the distribution of brighter pixels. A zone in this context was selected based upon the same pixel content and used to isolate a pixel set from the in situ layer of both galaxies. This in situ pixel set was placed over the abstract layer to enhance formations within the larger galaxy. The in situ inset also further emphasizes the homogeneity of color and texture of the smaller galaxy. The nuclear zone of the larger galaxy has contrasting shadowy elements in the abstract layer.

It is at this point of abstraction that one might imagine the larger galaxy is dynamically active and possibly drawing fuel and strength from the smaller galaxy. This is not to say that the smaller galaxy, 587727221950578719, might be drawing from a third source to accommodate both galaxies.

The third image in the series is the abstract layer less the in situ overlay. There are also 2 z .4 QSOs abstracted into the same layer. Another contour map was made with the QSOs appended into the in situ layer. This contour map follows the abstract zones very precisely. All image magnifications are the same.

It has been suggested in the literature that QSO venture from and to EV environments during their travel. During the trip QSO take on discreet (quantum-like) z-values that may be dictated by their local environment and 'ejection' strategy. The abstract layer has additional contours, or strokes, from pixel matches in the composited in situ layer. The green strokes are from set matches selected in the larger galaxy near the shadow boundary (AGN) of the outermost contour. The orange set stroke matches pixels selected from the larger QSO.

In the last image the contours and strokes are displayed over the inverted in situ layer. As mentioned above, the advent of a QSO journey might begin at the green and orange loci of the galaxy through a dynamic impetus of the entire system. The system evolves into an EV with identifiable galactic and QSO elements and eventually the QSO migrates away. How far it goes and whether it returns or it goes at all might depend on the system and other factors. The two QSOs in the images were chosen to represent a 'charged' and a 'spent' version of same object. Hypothetically the QSO acquires an elevated z-value in transit and then returns to a lower z-value as a 'diminished' object. It was purely by chance that the larger QSO has pixel a set in common with the larger galaxy. The other z .4 smaller QSO representing the 'spent' object is lacking an obvious pixel match. As an added note, the small object below the galaxy has a green stroke that is obscured by the contour map. The two bulges of the galaxies, delimited by the inner contours, have a median Photoshop luminosity of 161 and pixel count of 3,133. The larger QSO values are 141 and 978 respectively. (Size differences of QSOs may be exaggerated according to the way it is viewed.)



This is another galaxy pair at z .04, CGCG 385-062, with a similar (AGN) feature. The left-most galaxy is a different type and appears less passive. A nearby QSO z 2.09 situated east of this pair was inset and the pixels matched. The abstracted pixel set (red) around both nuclei is overlaid in the next image of the series. The green stroke is a pixel match from the QSO.

The last image in the series is a galaxy (or pair) at z .09 with a contour suggesting an interaction (influx) from a 'detached' arm. (There is a Chandra x-ray image of another galaxy with features like this at http://chandra.harvard.edu/photo/2010/eso137/.)

Collectively these images illustrate many aspects of possible EV (galaxy and QSO) relationships and life cycles. Quasars of the Milky Way have been reported.

Re:CGCG 385-062 NED01
J0118-0013. Both components of the S+S pair are well detected by IRAC and MIPS. The western component has a narrow-line AGN (Hao et al. 2005).
In its optical image, there is a blue, jet-like feature pointing to the companion galaxy. It is an LIRG, with log L_TIR_/L_sun_ = 11.41, dominating the
total dust emission of the pair. From aperture photometry of the IRAC bands, the AGN contributes ~ 40% of the dust emission of the galaxy. The
eastern component looks like a normal late-type spiral, contributing only ~ 12% of the L_TIR_ of the pair.

What can be a QSO?
« Reply #9 on: February 26, 2010, 02:02:08 AM »

NGC 7396 z .016, although not an obvious EV, does have features
which beg attention. Initially the corkscrew feature, center right, in the
upper panel reminds us of massive winding magnetic fields near galactic
nuclei. Opposite the core there is a jet-like feature.
(Unknown dust lane contribution.)



The lower panel has another rendering of the same area but this time
the features resemble propeller blades flaring from the core of the galaxy.
(There is an object at z 1.54 'nearby' and a curious galaxy
which at first glance looks like the 8 o'clock lens.)


Most EV described so far in this series may have a parent/offspring
relationship. NGC 7396 may evolve into a QSO and that's not to say
it has not 'seeded' other objects. There is interest in characterizing
which cosmic environments promote which ongoing development.

Reference provides galactic merger frequencies,
velocities of Gs with AGN and their spectra.
The inverted image is:

<Re: Possible strong gravitational lenses Reply #4640 on: April 10, 2010, 11:50:41 am>

(These elements will be themes in the next images.
M82, the GZ masthead, and others are mostly Seyfert galaxies.)

These last two panels are further examples of local
influences within galaxies. It should be noted that
the pixel rendering program and tools work best with
a limited range of z-values and galaxy sizes.
The left panel is the 'love machine,' z .028,
587741709404406068. It so was named because of
the heart-shaped object at the lower left.

The right panel, KUG 1016+460 IrS, z .064, has a
similar morphology. A nearby object,
587732483277652146 z .147, is inset and a pixel
content match is denoted by the green stroke. Three
regions in the image were enhanced to amplify internal structures.
(Compare z .189 G-like QSO)



Near AHZ60005uv there is a poster child for QSO (and AGN) with a clean spectrum with broad signals.

EV Rosetta Stone

Re-posted here below ...


EV Rosetta Stone

It might be time to digress and remove convention from the libretto. In many of the other EV posts there are comparisons of galaxies and q-objects. Cursory examination of images subjectively yields one interpretation. With more physical examination we can get a generous dose of scientific dogma attached to our view as well.

For this post, imagine what Young and Champollion thought when they translated the inscriptions on that ancient Egyptian stele - the Rosetta Stone. It was like opening a sealed jar and listening to a faint whisper from antiquity. The Rosetta Stone was not just linguistic wellspring. The scribe who marked that object recorded a missing link into a passing phase of culture.

Here we have an opportunity to explore another very ordinary object from antiquity and read what is contained on it. UGC 09401,
 z .018, v 5_628 has been Photoshopped for translation. This object may present the best argument in this series about whence q-objects arise. It is also very fortunate that specific targets in this SDSS image were chosen for analysis. (Ironically, these targets were chosen by an automated process.) Within UGC 09401 there appears to be 587739845920817185, z .086, v 5_628. Please note the v-values are the same. Please also note that the z-value of the latter, however. approximates that of the adjacent object 587739845920817184, z .087, v 26_096. The z-value of the other object is approaching that magical v > 30K 'Q-number.'

Two areas were enhanced in the image to emphasize the centers of the objects and their respective spatial positions. The red splotches are pixel matches within the boundaries of the contour maps.

(If this image were a GZ galaxy classification one might be tempted to intimate a merger or non-merger.)
If these objects represent an ongoing dispersion of components can we infer what drives the process?
Conversely if it is not a dispersion then how does one interpret this ancient artifact?

Zutopian mentions "I searched for 'UGC 09401' at the forum. It hasn't been posted in the UGC catalog thread yet! So you should post it also there!"

The pixels of AHZ2001gtq or DR6 587727944570896655. It has a spectrum.

Long story short, the blue areas of this image might indicate several possibilities of formation. In order to, perhaps, better understand what caused and/or contributed the structures their pixels were saved and compared with other AHZ - images. For the sake of brevity the set of pixels(sop) will be identified as z1-z7(7 zones.)

Photoshop provides several pixel manipulation apps and the sop was chosen and used throughout the comparative procedure with all AHZ- images. Images were chosen with relatively clear features to suggest an association of similar zones or activity. The first image is the exemplar with the ascribed zones. When this object is viewed during classification it almost looks like several image distortions. It is referenced by NED with AGN1 and lensing citations. There are 2 bright contributions in the image and NED also mentions a 'local' Galaxy Cluster.

Sources of sop2 ...
AHZ20018wu sop2 stroked AND AHZ20018wu curve with sop1 stroke (no spec)
AHZ200164u sop1 and sop2 strokes and poster core fill (no spec)
AHZ2001bjd ambiguous target and 1bjd in the same field (no spec)
AHZ2001gb8 spindly with fill and poster features (no spec)
AHZ2001gb8 2 more (AGN2) features added and sop1 stroke and fill (no spec)
AHZ5000g7o cigar with non-core feature (spec)

AHZ2000atj sop1 yellow/sop2 green with lensed feature (1 gtq exemplar zone 6) (no spec)
AHZ2000b3g another lensed feature (no spec)
AHZ2000f76 another lensed feature (no spec)
AHZ2001gtq sop1 target/cluster as lens (spec)

AHZ2000y2o candidate QSO with 1gb8 (AGN2) fill (no spec)
AHZ2000y2o examples of stroke tolerances and curve types


A sop is introduced into each image layer and then each zone is sampled from it to find matches in the image. When the image pixels correspond to a zone then the area is stroked with the color assigned to zone. The zone sample also becomes stroked in the process. AHZ20012g5, (no spec) above, also received additional pixel treatment (curve) after matching 4 of the sop zones. An additional sop2 from several contributing Hubble objects is used to stroke the third '12g5' image.(Near z5.7 LAE.)
12g5_1gb8_core_fill
The system/local_area_field includes 6 RadioSs out to .9, z1.1 GCluster out at .4 and 2 XraySs out to .7.

Newbie 24oct11_new  reply #27933 (faked lensed QSO?) The core of the spindly 'lower' object seems to be tethered to the rounder 'upper' object.
The classification target is a location where the 2 sop3 core features appear.
(Sop3-like pattern echoed in time-lapsed photo.)
There are other examples of Sy1/Sy2 field companions (which will get a reply of their own soon.)

This is a smaller but similar view of this unidentified system.
-0kgh_sop and -0kgh_bw have the cigar and companion with a sop3.
(The images have inserts of more 'active' field neighbors.)


Larger and smaller objects with stroke patterns ...
AHZ2000wq1 orange sop2 filled AND AHZ2000wq1 curve and just sop2 strokes. (no spec)
0wq1 with a shared independent black stroke and sop1 and blue sop2.
Owq1 with sop2 and sop3 feature in the green nest region with projecting 1bjd fills.
AHZ2001ho3_sop and AHZ2001ho3_bw two or more smaller objects possibly a train. Sop3 core feature in the larger, partial, object.

2-Object stroke pattern ...
AHZ2000f8m sop1 strokes with curves inset AND AHZ200182u image, like 0f8m, fill-stroked (near prG?) (no spec, NED)

AHZ2000txd sop1 strokes and curve inset AND AHZ2000txd sop2 strokes (train-like 1bjd features) and another with a nested sop3 feature (no spec, NED)


Posts are works in progress, enjoy.

AHZ2001bjd, or 1bjd, was randomly chosen as a sop2.
Here are a few of the many Gs and field companions with the 1bjd stroke.

GPair at z.6: the target has a nested sop3. The first image, AHZ2000pn9, is broadly stroked with a curve inset
and other two highlight the finer structure and differences of the pair.
(In reply 13 there are more examples strokes of targets and companions with the larger objects poster-3 blot.)



AHZ2000gkw was mistakenly found while looking for -0kgw. It was an amazing mistake. (Both objects are very interesting.)
The quotes from two papers supply the colloquy.
The first image includes sop1 strokes with sop3 features as reference points.
This image has the sop2 strokes and fill with the sop3 features.
As a pean to new things, and others in the next thread post, this image renders the distribution of selected strokes.

Quote
Nearly half of them are spatially extended with a size larger than 0.15 arcsec (~0.88 kpc at z = 5.7) and up to 0.4 arcsec (~2.5 kpc at z = 5.7). The others are nearly unresolved compact objects. Two LAEs show double-component structures indicating interaction or merging of building components to form more massive galaxies.

Quote
We find a total of 119 LAE candidates at z~5.7. Over the wide-area covered by this survey, we find no strong evidence for large-scale clustering of LAEs. We
estimate a star formation rate (SFR) density of ~7x10^-4^ M_sun_ yr^-1^ Mpc^-3^ for LAEs at z~5.7 and compare it with previous measurements.

This is a more expansive view of -0kgw here in a post.

In the post AHZ2000kgw is situated along a string of objects.
(-0kgw has tightly-wound, swirling features that appear in other objects and QSOs.)
(errata: target fill from sop3 exemplar has wrong overlay)
Another, less tightly, wrapped G and one tightly wrapped G.

Sop1(yellow) and sop2(1bjd) field ratios with poster(3,) and poster(2,) b&w galaxy contribution
to accentuate the sop features.

03po_bw, 11dk_bw, 0wq1_bw, 1iqh_bw,
1bjd_bw, 164u_bw, 18wu_bw, 12g5_bw, 10x3_bw

AHZ2000f7b odd location and forms for sop3 features. sop1, sop2

AHZ2001ho3 like -0f7b above with sop3 features and an odd z-value.
This is another rendition of -1ho3.




This target has a lot going for it without much baggage. AHZ20003xj_bw has no info other than the ID and z. It is a poster child for the
often described afferent object interacting with another object. It could also be a disrupted tier system as mentioned in another reply.
It may be a system like AHZ400008l. More information would be welcomed for these two systems.

Continuation of topic reply 8 ...


AHZ2001kxi z.3, AHZ2000vj4 z.6, near AHZ20018mo z1.02



Both objects IDed 587727944033829482 @/near -12qk and a sep.138 RadioS/lens @ z.7


AHZ2001iim is a practically naked core object feature seen nested in many other fields.
The object begs the question, where is the rest of the object?


http://cas.sdss.org/dr6/en/tools/explore/obj.asp?id=588015508209401994 posted edge-on wide Ha and flare feature


AHZ200068n is in an 'active' zone.

From a recent post of a field neighbor, this target
has a Sy2 foci in a larger, well defined system.
There are more features that appear to be removed
from the target in the foreground. It is hard to make
out if the compact blue item is a star.


AHZ2000avb is included in this reply to show the
centers of activity in this (extended) system.

The redshift is actually z.2-.6phot and remarkably there are
no mentions of any survey measurements other than the
inset RadioS and XrayS.

The poster feature colors are similar to the assigned,
derived colors so take care to note the differences. Here
the tilted, larger companion has an AGN2 red stroke atop
the presumptive barred core.  It is likely the asymmetry
(of features) are apropos of this epoch and we are not
missing any obscured (active) parts.

It is easy to assume that the 'extension' of the 'core' and the
adjacent 'active' region at the tip are representative of a step
in the life-cycle of the target. At the other end of the companion
there is a 'faded' 'active' region. Might that indicate the core
extension rotated past it or did it have its own extension at
another time?
