NGC 4835
Galaxy in the constellation Centaurus
From Wikipedia, the free encyclopedia
NGC 4835 is a intermediate spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is 2,441±19 km/s, which corresponds to a Hubble distance of 117.4 ± 8.3 Mly (36.01 ± 2.54 Mpc).[1] However, 18 non-redshift measurements give a much closer mean distance of 75.63 ± 2.73 Mly (23.189 ± 0.836 Mpc).[2] It was discovered by British astronomer John Herschel on 3 June 1834.[3]

NGC 4835 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]
Galaxy group
NGC 4835 is part of a galaxy group known as [CHM2007] LDC 939 which contains four galaxies, including NGC 4976, ESO 219-21, and ESO 269-58.[6][7]
