NGC 4419 is a barred spiral galaxy in the constellation of Coma Berenices. It was discovered by German-British astronomer William Herschel on 8 April 1784.[2]
NGC 4419 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[3]
Distance
NGC 4419 has a velocity with respect to the cosmic microwave background of 64±23 km/s, which is too small to be used to estimate its distance.[1] Instead, 22 non-redshift measurements are used to give a mean distance of 52.49 ± 2.51 Mly (16.095 ± 0.771 Mpc).[4]
Supernovae
Two supernovae have been observed in NGC 4419:
- SN 1984A (Type Ia, mag. 16) was discovered by Givi N. Kimeridze on 4 January 1984, and independently by Leonida Rosino (bio-it) on 7 January 1984.[5][6][7]
- SN 2012cc (Type II, mag. 18.2) was discovered by the Lick Observatory Supernova Search (LOSS) on 29 April 2012.[8][9]
