NGC 3074 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 5,395±18 km/s, which corresponds to a Hubble distance of 259.5 ± 18.2 Mly (79.57 ± 5.58 Mpc).[1] It was discovered by German-British astronomer William Herschel on 28 March 1786.[2][3]
NGC 3074 is an active galaxy nucleus candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4]
Supernovae
Three supernovae have been observed in NGC 3074:
- SN 1965N (Type II, mag. 15.8) was discovered by Polish astronomer Konrad Rudnicki on 21 December 1965.[5][6]
- SN 2002cp (Type Ib/c, mag. 17.9) was discovered by LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches) on 28 April 2002.[7][8]
- SN 2019bqe (Type Ia, mag. 18.2) was discovered by Xingming Observatory Sky Survey (XOSS) on 7 March 2019.[9]
