Object name: ARP096
Arp 96 falls under Arp's category for spiral galaxies with elliptical galaxies on their arms. They are located 205 million light-years away based on their redshifts which are virtually identical. But we can't say the elliptical is on the arm of the spiral. It would be better to say it appears to be on the arm. If it really were I suspect the arm (more a plume) would be more highly distorted. Arp stated his categories as if they were fact when they were more how they appeared to him. In some cases the galaxy on a spiral's arm is now known to be a far distant galaxy. His other categories were often incorrect. Especially those that he said categorized as material ejected from the nucleus. That's not true for any in that category that I've been able to determine. In this case, their redshifts are virtually identical indicating they are closely related but that doesn't mean one is on the arm of the other. Still, interaction likely is why the spiral's arms are so distended. Also, note the faint arc of stars at the southern end of the lower galaxies halo about halfway to the red star below it. Why is this short arc so well defined? I found nothing on it.
