Object name: ARP132
Arp 132 falls in Arp's category "Elliptical close to and perturbing spirals." It is about 350 to 360 million light-years away in the constellation of Leo just north of Crater. It appears the western galaxy is the spiral and the eastern the elliptical that Arp refers to. Oddly NED classes both as E pec one place and the obvious spiral as Sb pec in another. It appears the E pec classification is a misprint. The redshifts of these two aren't quite the same indicating an 8 million light year difference. This doesn't mean they are really this far apart or didn't interact in the past. Still, I have problems with them as a real interacting pair. The elliptical, while labeled peculiar, probably for the strong core and much weaker outer areas (is this a disk seen face on or a sphere of low stellar density) it is quite even. I'd suspect any recent interaction to have distorted it in an unsymmetrical way. There are a few other galaxies at about the same distance in the image including the far larger CGCG 011-062 to the far left of my image. None of them appear likely candidates either for interaction with the western member of Arp 132. Is an interaction even necessary as these are quite small galaxies some of which just seem naturally distorted? Another possibility I didn't find anyone considering is that the southern part of the spiral is really a separate galaxy with a tidal tail looking like a spiral arm so this is a merger in progress. I found virtually nothing of use for deciding this in the literature.
