General information
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]
Supernovae
Three supernovae have been observed in NGC 4088:
- SN 1991G (Type II, mag. 17) was discovered by Jean Mueller on 10 February 1991.[10][11]
- SN 2009dd (Type II, mag. 13.7) was discovered by Giancarlo Cortini on 13 April 13, 2009.[12][13][14] At apparent magnitude 13.8,[14] it became the third-brightest supernova of 2009.[15]
- SN 2022jzc (Type II, mag. 17.8) was discovered by the Zwicky Transient Facility on 16 May 2022.[16]
