NGC 4914 is an elliptical galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 4,816±22 km/s, which corresponds to a Hubble distance of 231.7 ± 16.3 Mly (71.04 ± 4.99 Mpc).[1] However, three non-redshift measurements give a much closer mean distance of 111.76 ± 21.42 Mly (34.267 ± 6.567 Mpc).[2] It was discovered by German-British astronomer William Herschel on 17 March 1787.[3][4]
NGC 4914 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.[5][6]
NGC 4914 group
[edit]NGC 4914 is the namesake of the NGC 4914 group (also known as LGG 319) which has at least 3 members. The other two galaxies are NGC 4846 and NGC 4868.[7][8]
