NGC 4051 is an intermediate spiral galaxy in the constellation of Ursa Major. [2] It was discovered on 6 February 1788 by John Herschel. [5]

Contents

NGC 4051 contains a supermassive black hole with a mass of 1.73 million M☉. [6] This galaxy was studied by the Multicolor Active Galactic Nuclei Monitoring 2m telescope. [7]

The galaxy is a Seyfert galaxy that emits bright X-rays. However, in early 1998 the X-ray emission ceased as observed by the Beppo-SAX satellite. X-ray emission had risen back to normal by August 1998. [8]

NGC 4051 is a member of the Ursa Major Cluster. [9] [10] [11] Its peculiar velocity is −490 ± 34 km/s, consistent with the rest of the cluster. [3]

Supernovae

Three supernovae have been discovered in NGC 4051:
