This was one found by antikodon that I remembered HAndernach commented on: http://radiotalk.galaxyzoo.org/#/subjects/ARG00036hs

If you click the link, you'll see that zooite antikodon wrote, on January 27 2014 2:11 PM, "#overedge #doublelobe host (?)"; HAndernach (SCIENTIST) replied, at 8:49 PM the same day, "SDSS J132435.81+084635.5= ASK 482820.0, an IR- and HI emitting spiral with an FRII morphology, EXTREMELY RARE, should be followed up!"

Here is SDSS J132435.81+084635.5 (DR10), a galaxy whose morphology is classified as "Spiral" in GZ1, and whose spectroscopic redshift is 0.044:



And here is a FIRST image, centered on the brighter lobe (the spiral is about midway between the two faint, extended sources):



Sorry, there are no radio source at the left of the spiral opposite to the radio lobe of ARG00036hs. I see only noise.

You could check by a FIRST Catalog Search on the position of the spiral 1237671956441596126 at coords 13:24:35.81, +08:46:35.57  with a radius of 4.5 arcmin.

Redo this search for having images on clicking the links provided in the results.

To me, Object FIRSTJ132430.2+084654 looks like a hourglass without optical counterpart  :(

Here's a composite FIRST + SDSS image; note that the E lobe (on the left) is pretty faint, but seems to be above the general noise (scale is 0.36"/pix):



And here's a triple composite, NVSS (in cyan) + FIRST (red) + SDSS (same scale):



The resolution of NVSS is much lower than even WISE; in fact, the whole image is only a few 'resolution-elements' wide!  :P Nevertheless, it seems that the E lobe is quite real.  8) Maybe I should produce an even more zoomed-out composite image ...

This will likely be the last candidate I post here for a while (PM me if you'd like to know why  ;)). SDSS J120339.20+275537.2, ARG0001uiz was first commented on by WizardHowl (I think), and is another example of a double lobe/jet with only one being visible in FIRST (the other is clear in NVSS).

The likely host galaxy itself is very modest, but its DR10 morphology is definitely not that of an elliptical ('pointy ends', ellipticity too extreme):



FIRST + SDSS composite, scale is 0.36"/pix:



To illustrate what DocR (Lawrence Rudnick) means*, here's an NVSS + FIRST composite, with the same scale (I'll do a 'zoomed out' NVSS + FIRST composite later):



Here's his own pair of images** (FIRST then NVSS):



* "This is another beautiful example where there is a weak lobe on the other side of the core/black hole, but it has no small-scale structure, so it is only visible in NVSS [...]. So it's a #triple of which only part is visible in FIRST."

** "This is a beautiful, unusual source. There is another lobe to the lower left, seen in NVSS, but not in FIRST. But then, to the upper right (NW) is an orphaned source, no optical ID, and not clear who it belongs to"

My apologies for my first interpretation as noise of your hint of opposite lobe.

I reprocessed the FIRST cutout fits file and got this image in tweaking by Aladin tool:



I agree that the east lobe seems real, probably in a less gas cloud environment than for west lobe.

The linear distance is ~2.81arcmin i.e. 145.5 kpc at redshift 0.0444  8)

Following this thread with considerable interest - some colleagues set a summer student looking through GZ+radio survey data, and found one plausible spiral with double sources. Zooites are far beyond that already. One possibly helpful point - the FIRST data were taken in a VLA configuration optimized for ~arcsecond resolution and detection of compact sources. Another VLA survey, the NRAO VLA Sky Survey (NVSS), was optimized for larger-scale structures and often shows very extended lobes more clearly. (It is a feature of interferometric imaging that only structures on a certain range of angular scales are shown with high fidelity - large, smooth image components are "resolved out" and can essentially vanish if no further data are available, one reason it's common for the (J)VLA to observe the same target in more than one of its size configurations). NVSS FITS cutouts of a desired sky area can be obtained here.

Here's just such "an even more zoomed-out composite image" (scale is 0.72"/pix):



As  HAndernach noted, over in RGZ Talk, "by the way, the eastern (left) lobe appears like noise in FIRST, only because it's very diffuse; look at NVSS: it is almost as bright"

The paper referred to is "A 20 centimeter VLA survey of Abell clusters of galaxies. II - Images and optical identifications", by Owen et al. (link to ADS entry). Here's the abstract:

Quote from: Owen+ 1992
Radio contour maps, models, and optical identifications for 130 radio galaxies in Abell clusters of galaxies are presented. Results of Gaussian model fits to sources smaller than two beamwidths are presented. The observations were made between 1979 and 1984 using the VLA at 20 cm.

There's an image of Abell 1455 in that paper - which I'll try to copy and post here later - in which they seem to associate the main radio lobe (in the FIRST + SDSS composite, 0.36"/pix image above) with a different galaxy ... making this plus the "to the upper right (NW) is an orphaned source" a double lobe!  :P

Did any GZ zooites discover unusual radio galaxies? is the title of a thread I began earlier today, over in RGZ (Radio Galaxy Zoo) Talk.

Here's what I posted (extract):

Quote
As of just now, there are 262 posts in the GZ forum's Radio source thread, dating from December 09, 2007.

Many posts in that thread report a positional (on the sky) co-location of an SDSS object - usually a galaxy - and a radio source as identified in an online catalog, often NED; quite a few posts do not report the source for the radio object.

[...]

Is there a reasonably straight-forward way of checking what zooites have posted in that thread?

For example, how to obtain a FIRST image, with the appropriate 'plate scale', and overlay it on the SDSS image of what is obviously a spiral galaxy (to see, for example, if it's an hourglass or doublelobe, or if there's a jet)?

New paper:

Mega parsec relativistic jets launched from an accreting supermassive blackhole in an extreme spiral galaxy
Quote
Here we present the discovery of giant radio source J2345-0449 (z=0.0755), a clear and extremely rare counter example where relativistic jets are ejected from a luminous and massive spiral galaxy on scale of ~1.6 Mpc, the largest known so far.

In the paper there is shown an SDSS image and the coordinates are given as follows.:
"the nucleus of the spiral galaxy at right ascension: 23h 45m 32.71s , declination: −04◦ 49′ 25.32  ′′ (J2000)",

An Unusual Radio Galaxy in Abell 428: A Large, Powerful FR I Source in a Disk-Dominated Host
Quote
The optical and NIR images clearly show a disk. We detect apparent spiral arms and a dust-lane from B band imaging.
Quote
To the best of our knowledge, this is the first reported detection of a large-scale FR I radio source in an unambiguously disk-dominated host galaxy.

I never even noticed that paper was submitted on my 40th birthday!

The case for spirality was made even more strongly by later Hubble images, like this ACS composite overlaid with the VLA radio structure:


described in
The Spiral Host Galaxy of the Double Radio Source 0313-192
.

If we could glue together pieces of Galaxy Zoo and Radio Galaxy Zoo... (there has been a bit of messaging across the teams on the value of spiral hosts of giant double radio sources)

We report B,R,J, and K imaging, optical spectroscopy, a rotation curve, an IRAS detection, and a VLA 20cm image for this galaxy, 0313-192.

http://arxiv.org/abs/astro-ph/9709213

and the subsequent paper
 
"The Spiral Host Galaxy of the Double Radio Source 0313-192"
Quote
We present new Hubble, Gemini-S, and Chandra observations of the radio galaxy 0313-192, which hosts a 350-kpc double source and jets, even though previous data have suggested that it is a spiral galaxy.
by William C. Keel, Raymond E. White III, Frazer N. Owen, Michael J. Ledlow
http://arxiv.org/abs/astro-ph/0608086

are about the same galaxy!
Curiously, there is a long period of time between the submission dates.: One was submitted 1997 and the other one 2006 !

Catch up, and collection. I'll edit/update this post periodically. Current status: I'm working my way through the "not yet rated" candidates, and also checking the ones I'd rated earlier, for consistency. I'll also be editing some of the "images" posts, to provide consistent info (and may add some new images).

In this post: possible lobe/jet radio source apparently associated with disk galaxies (a.k.a. spirals), as identified independently by zooites, and posted anywhere in RGZ Talk. Together with discoverer, link to discovery RGZ comment/post/thread, and link(s) to nice composite images. Different lists for ratings "excellent", "good", "fair", "poor", "else", and "haven't rated yet". Rating is a WIP (see below)

Quasi-columns: RGZ ID, SDSS ID, zooite, discovery link (and date of discovery), image(s) link(s), redshift ("ph"= photometric, "sp" = spectroscopic), note (if any); | character as separator. Order is timestamp on discovery comment/post/thread, most recent ones last.

Excellent (N=8 ... +1  ;))

About those criteria: I have just finished writing a post on the background (direct link). I'm going to use a simple two-part test, taken independently/in parallel: is this galaxy
  • the likely host of the "beyond the optical boundary" radio emission?
  • not a boring elliptical?

A candidate is rated "excellent" if the answers are (Yes! Yes!); "good" if (Yes! yes), (yes Yes!), or (yes yes); "fair" if both are at least 'maybe/perhaps' (but is not "excellent" or "good"); "poor" if at least one is 'cannot really tell' (similarly); "else" for all others. Answers ranking: Yes!, yes, maybe/perhaps, cannot really tell, likely not, certainly not.

In case anyone else would like to work on the objects in my file, I've posted the ARG and (where applicable) SDSS IDs of many of the objects in my file, that I'd classed as "poor" or "else" (the distinction is somewhat arbitrary, for those I posted). As I work though the file, I'll post the rest.

Anything else to add? Yes; Work on making the criteria for the ratings more objective.

Please let me know of any mistakes you fell I made, or any corrections, or additions I should make; comments, suggestions: all are welcome!  :)

Re: Friday, 21 February, 2014: Very Strange Spirals?
« Reply #29 on: June 09, 2014, 04:47:38 pm »
This post is like the previous one, and I'll likewise update/edit it periodically.

In this post: possible lobe/jet radio source apparently associated with disk galaxies (a.k.a. spirals), as identified independently by zooites, and first posted other than in RGZ Talk (may be subsequently mentioned in the Hourglass sources associated with spiral galaxies RGZ Talk thread, or not). Together with discoverer, link to discovery (non-RGZ) comment/post/thread, and link(s) to nice composite images. Specifically excluded: reports of such associations previously published, or noted (in the literature for example).

Quasi-columns: SDSS ID, zooite, discovery link, image(s) link(s), note; | character as separator. Order is as they appear in this thread, then pretty much as I find them.


It may take quite a while to put together a list in this form ... so I'll just note, for now, candidates (with at least one link to further info):
  • FIRST J084000.8+294838 | SDSS J084002.36+294902.6 | z_sp 0.06484 | Sy2 Sc D. NOT a boring elliptical; see c_cld's post on this, on p1 of this thread (here)
  • (did any zooite notice SPECA independently? before 2011??)
  • SDSS J135217.88+312646.4  1237665331471515679 z spec=0.0452 UGC 08782 , UGC 8782,  FIRST J135217.8+312646  , 3C 293.0 , 3C 293. NOT a boring elliptical; c_cld noted the jet/lobe here; the galaxy itself has been posted several times, perhaps earliest by RandyC
  • SDSS J132738.22-020309.9 1237655499200528553 zspec=0.183  4C -01.29. NOT a boring elliptical, and has x-shaped radio emission (per c_cld; did some zooite post it, under its DR7 ID?)
  • SDSS J083752.75+445025.9 1237654653102653683 z spec=0.207 2MASX J08375276+4450255  -- Seyfert 2 Galaxy. Likewise NOT a boring elliptical (see c_cld's post)
  • SDSS J011341.10+010608.5 1237666340800364769 FIRST J011341.1+010609 -- Seyfert 2 Galaxy oiii_5007_flux 2118.05 1237666340800364770 "Winged" and X-Shaped. NOT a boring elliptical (c_cld, quoting a Jan 2012 post of his)
  • SDSS J132318.81+030807.1 1237651737376653585 4C +03.27. NOT a boring elliptical (c_cld)
  • SDSS J023832.67+023349.1 PKS 0236+02 2MASX J02383267+0233496 CXO J023832.6+023349 not a boring elliptical? (my post, quoting TonyWei's)
