Arp 299(parts of it also known asIC 694andNGC 3690) is a pair of colliding galaxies approximately 134 millionlight-yearsaway in theconstellationUrsa Major.Both of the galaxies involved in the collision arebarred irregular galaxies.NGC 3690 was discovered on 18 March1790byGerman-BritishastronomerWilliam Herschel.[1]
It is not completely clear which object is historically calledIC 694.According to some sources, the small appendage more than an arcminute northwest of the main pair is actually IC 694, not the primary (eastern) companion.[2][3]
The interaction of the two galaxies in Arp 299 produced young powerfulstarburst regionssimilar to those seen inII Zw 96.[4]Since 1992, fourteensupernovaehave been detected in Arp 299: SN 1992bu (type unknown, mag. 16.6),[5]SN 1993G (type II,mag. 16.6),[6]SN 1998T (type Ib,mag. 15.4),[7]SN 1999D (type II, mag. 15.6),[8]SN 2018lrd (type Ib, mag. 17.1),[9]AT 2018mel (type unknown, mag. 16.5),[10]SN 2019lqo (type II, mag. 18.3),[11]SN 2020fkb (type Ib, mag. 17.8),[12]SN 2022gnp (type Ib, mag. 17.7),[13]SN 2023wrk (type Ia,mag. 18.1),[14]and SN 2024gzk (type IIb, Mag. 17.8)[15]were observed in NGC 3690, while SN 2005U (type II, mag. 16.2),[16]SN 2010O (type Ib, mag. 15.6),[17]and SN 2010P (type unknown, mag. 18.3)[18]were observed in IC 694.[19][20]
