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]

Disk Structure

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]

Galaxy group information

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]

Supernova 2009dd

On April 13, 2009, SN 2009dd was discovered in NGC 4088.^[10] At apparent magnitude 13.8,^[10] it became the 3rd brightest supernova of 2009.^[11] In 1991 there was SN1991G.
