IC 883

IC 883 (also known as Arp 193, IRAS 13183+3423, PGC 46560 and UGC 8387) is an irregular galaxy that is about 321 million light years away from Earth. It is located in the constellation Canes Venatici. Its largest radius is 1.4 (131 thousand light years), and smallest 0.7 angular minutes (65 thousand light years).^[b] It was discovered by Rudolf Ferdinand Spitaler on May 1 1891.^[2][4][5]

IC 883 is classified a luminous infrared galaxy (LIRG).^[6][7] It is a recent merger given that the galaxy has one single nucleus and two tidal tails. The molecular gas measured in IC 883 is estimated 4 x 10⁹ M_Θ.^[8] It is known to show a radio jet originating from its nucleus travelling at a subluminal motion of 0.6-1 c.^[9]

Two supernovae have been observed in IC 883: SN 2010cu (type II, mag. 17.7),^[10] and SN 2011hi (type II, mag. 17.9).^[11] When observed in near-infrared or optical wavelengths, they are the nearest supernovae found to the nucleus of an LIRG.^[12]
