IC 883
Irregular galaxy in the constellation Canes Venatici
From Wikipedia, the free encyclopedia
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 billion MΘ.[8] It is known to show a radio jet originating from its nucleus travelling at a subluminal motion of 0.6-1 c.[9]
Supernovae
Two supernovae have been observed in IC 883:
- SN 2010cu (Type II, mag. 17.7) was discovered by S. Mattila and E. Kankare on 24 February 2010.[10][11]
- SN 2011hi (Type II, mag. 17.9) was discovered by E. Kankare, S. Ryder, and S. Mattila on 11 February 2011.[12][13]
When observed in near-infrared or optical wavelengths, they are the nearest supernovae found to the nucleus of an LIRG.[14]
