NGC 4088 is an intermediate spiral galaxy in the constellation Ursa Major. The galaxy forms a physical pair with NGC 4085, which is located 11′ away. [4]
NGC 4088 is a grand design spiral galaxy. [5] This means that the spiral arms in the galaxy's disk are sharply defined. In visible light, one of the spiral arms appears to have a disconnected segment. Halton Arp included this galaxy in the Atlas of Peculiar Galaxies as one of several examples where this phenomenon occurs. [6]
NGC 4088 and NGC 4085 are members of the M109 Group, a group of galaxies located in the constellation Ursa Major. This large group contains between 41 and 58 galaxies, including the spiral galaxy M109. [7] [8] [9]
Three supernovae have been observed in NGC 4088. The first was discovered on 10 February 1991, SN 1991G ( Type II, mag. 17). [10]
On April 13, 2009, supernova SN 2009dd was discovered in NGC 4088. [11] At apparent magnitude 13.8, [11] it became the third-brightest supernova of 2009. [12]
On 16 May 2022, SN 2022jzc was discovered ( Type II, mag. 17.8). [13]
