Arp 107

Arp 107 is a pair of interacting galaxies (designated separately as UGC 5984 and MCG+05-26-025) located about 450 million light-years away in the constellation Leo Minor.

The nucleus of PGC 32620 is active and it is classified as a type 2 Seyfert galaxy.

[6][7] Additionally, the galaxy is depicted having a ring-like appearance.

The most likely scenario for this appearance in PGC 32620, is that the elliptical galaxy penetrated through its disk, causing it to become semi-annular with a large single spiral arm protruding out.

[4][7] This spiral arm in turn, then branches out in a form of a tidal arm, where star-forming regions of both old and young star populations are present.
