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).[1] It was discovered by British astronomer John Herschel on 1 May 1834.[2]
NGC 5419 is the brightest cluster galaxy of the galaxy cluster, Abell S0753.[3] 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.[4][5][6]
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.[7]
- SN 2020alh (Type Ia, mag. 15.3) was discovered by ATLAS on 19 January 2020.[8]
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.[9]
