Object name: ARP109
Designation(s): ARP109, IC4416, IC4417,
Arp 109 is in Arp's class for "E and E-like galaxies repelling spiral arms", a class that never has made sense to me. If it has spiral arms isn't it a spiral galaxy? What is a "repelling spiral arm?" In any case, it includes two galaxies, one a true elliptical to the east and a very strange disturbed spiral to the west. It seems to have two plumes both curving to the west. Were these plumes created by interaction with its large companion? The companion shows no sign of distortion. Could the outer plume be due to the remains of a small galaxy the western member is digesting? I found nothing to help with this issue.
