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).^[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]
