NGC 5419
NGC 5419 is a large elliptical galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is 4,375 ± 23 km/s, which corresponds to a Hubble distance of 64.5 ± 4.5 Mpc (∼210 million light-years). It was discovered by British astronomer John Herschel on 1 May 1834.
NGC 5419 is the brightest cluster galaxy of the galaxy cluster, Abell S0753. It contains a large core with a radius span of 1.58 arcsec (≈55 pc). In addition, it has a double nucleus, indicating the presence of two supermassive black holes in the center with a separation gap of only ≈70 pc.
Supernovae
Two supernovae have been observed in NGC 5419:
- SN 2018zz (type Ia, mag. 16) was discovered by the All Sky Automated Survey for SuperNovae (ASAS-SN) on 3 March 2018.
- SN 2020alh (type Ia, mag. 15.3).
NGC 5488 Group
According to A.M. Garcia, the galaxy NGC 5419 is part of the NGC 5488 group (also known as LGG 369). This group of galaxies has 14 members: NGC 5397, NGC 5488, IC 4366 and nine galaxies from the ESO catalog.
