Collisional Ring Galaxies
-
I have been collecting ring galaxies with another galaxy nearby, suggesting the ring galaxy formed after a collision with the other galaxy. I found a nice video portraying this:
https://www.youtube.com/watch?v=4kxk62PNHlcI am going to post my possible collisional ring galaxies over here.

This subject has been covered on the old Galaxy Zoo Forum too:

I'll go through my merger, g-pair and ring galaxy collection to see what I have to add

And one more - they seem to be turning up in the lens collection!
I will be honest, this one is not likely to be a collisional ring, but there is enough doubt in my mind to include it 😃

And another from the lens collection.... 😃

Maybe this one too? Could also be a polar ring.

possibly in the process of collision?

That's a stunning one.
Anyone keeping track of how many of these are in existing ring catalogs, like the original GZ paper? http://adsabs.harvard.edu/abs/2012MNRAS.422.2386F
It'd be important to keep track if any of these are potentially new!

A lot of them are previously referenced on NED, but apart from the old 'Hoag Type galaxies and Collisional rings' thread on the forum, no list exists.
I have a bit of spare time, so I guess I could start documenting them in a collection.
Edit - collection created CGZL00006q - will start to tag the examples contained in this thread, along with whether they are known or not.

That'd be great - definitely a first step toward turning these into a more complete catalog.

This thread has now been documented, collected and added to the spreadsheet. Will now be merged into a pre-dating collisional - ring thread.

Candidate; DECaLS SDSS , couldnt find it in the existing collection
Edit TEMP 2 till crosschecked for GZ ID, i know i know

by Capella05 moderator in response to Ghost Sheep SWR's comment.
The existing collection is a work in progress - I do have a life away from GZ 😃
Once again please post the ID! It cannot be added to a collection or a GZ catalogue without an ID!
Posted
-
Ok, you cant create / give it a GZ ID?
Posted
-
by Capella05 moderator
No 😃 It doesn't work like that.
ID's are assigned at the beginning of a dataset, when the images are prepared for classification.
Did you classify the object involved? If so, it will be in your recent history tab on the classification interface. Otherwise it is going to be difficult to match up with an id.
Posted

I didnt, and its still missing 1 or more color filters so likely not in current dataset. Ah well, carry on. ( ps a life outside GZ, how quaint 😉 )

Here's an SDSS image, centered on z_sp 0.089 SDSS J211407.35+103634.4:
As far as I can tell, it's not among the GZ Talk collisional ring Collection. According to NED, there are a number of papers which include this interacting pair (more?) of galaxies.
If anyone is interested, it may be possible to 'reverse-engineer' the Dec-AGZ Id correlation, to get a handle on whether this already has a DECaLS AGZ ID (accessible via GZ); certainly in RGZ this correlation can be used to find an ID from an object's Dec (see here for details)
Posted

Very informative thank you, but above me im afraid. I wonder why it isnt possible to simply search on RA DEC ( which is linked to an ID; visible under the object image)

Good question, @GhostSheepSWR, and thanks for the answers, @Capella05 and @JeanTate. A reverse search by coordinates would be a nice addition to Talk or the analysis tools. I'll bring it up with the developers, but couldn't promise it'd be added any time soon, as there are a lot of higher priority issues they're working on. One possible avenue would be to maintain a thread of such coordinates, and I can try to check them manually when I can.
That particular galaxy doesn't have a DECaLS image in Galaxy Zoo (even though it's an excellent example of an interacting ring) since it's missing one of the filters, exactly as you said.

It would be good to be able to add markers to a sky map, as on Google Sky. A galaxy can have twenty IDs, but only one location on a sky map.

by Capella05 moderator
The RA / DEC is recorded in the spreadsheet associated with the collection. Easy enough to export 😃

Over in RGZ Talk, KWillett started a thread called I have a position, how do I find which ARG fields contain it (if any)? SOLUTION.
The solution should work very well for RGZ fields, if you use the Python code or a spreadsheet, and in principle could be repeated for almost all GZ projects (e.g. DECaLS and UKIDSS, but not Illustris).

Might this be a candidate, or some other form of disturbance?
Edit: outside DECaLS bounderies, SDSS9:

So do you think that this smaller galaxy may have done the damage

Will be going through and updating the list this weekend.
Has anyone been cataloguing polar rings?
