UGC 12914 UGC 12915 Taffy Galaxies
-
Out of interest and for a new project I'm starting I wanted to collect all known Voorwerpjes including those not found by Galaxy Zoo.
According to Wikipedia (Hanny's Voorwerp) there are two others, NGC 7252 (not in SDSS) and UGC 12914 - 12915 (Taffy Galaxies). The first thing that I thought was strange is that the presumed Taffy Galaxies Voorwerp is unreferenced in Wikipedia.
On further searching in SIMBAD I could indeed find no paper referencing the Taffy Galaxies mentioning Voorwerp, Voorwerpjes, EELR, AGN ionization echo or something similar.
So it seems the Wikipedia page on Hanny's Voorwerp is incorrect to mention the Taffy Galaxies as second non-GZ Voorwerp host. Perhaps misunderstood or personal preference of the Wikipedia editors?
Also as Budgieye mentioned in the comments and indicated in the old forum, this blog considers the green area below UGC 12915 to be H-alpha emissions not [OIII] 5007 emissions.

So what is the GZ consensus on the Taffy Galaxies?

I don't know of any evidence they have an AGN-ionized cloud (although seeing an appropriate spectrum could change that, of course).

in response to NGC3314's comment.
I suspected as much. Doubt the editors know something more you wouldn't be aware of.
Thank you for the confirmation / feedback.
