NGC 4619 is a barred spiral galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 7,176±18 km/s, which corresponds to a Hubble distance of 345.2 ± 24.2 Mly (105.84 ± 7.41 Mpc).[1] However, 15 non-redshift measurements give a closer mean distance of 331.74 ± 12.34 Mly (101.713 ± 3.783 Mpc).[2] It was discovered by German-British astronomer William Herschel on 1 May 1785.[3]
NGC 4619 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[4][5]
Supernova
One supernova has been observed in NGC 4619:
- SN 2006ac (Type Ia, mag. 16.0) was discovered by the Lick Observatory Supernova Search (LOSS) on 9 February 2006.[6][7]
