NGC 4458

May 03, 2024

NGC 4458 is an elliptical galaxy located about 54 million light-years away[3][4] in the constellation of Virgo.[5] It was discovered by astronomer William Herschel on April 12, 1784.[6] NGC 4458 is a member of Markarian's Chain which is part of the Virgo Cluster.[7] It is in a pair with the galaxy NGC 4461.[8] NGC 4458 and NGC 4461 are interacting with each other.[9]

NGC 4458 may have a supermassive black hole with an estimated mass of 200 million Suns (2×108 M☉).[2]

Nuclear disk edit

NGC 4458 has an edge-on nuclear disk which is estimated to be about 6 billion years old.[10] The disk likely formed from the merger of a gas-rich galaxy and has been found to have "similar properties to the decoupled cores of bright ellipticals".[11] [12]

Counter-rotating core edit

Using Hubble images, it has been determined that NGC 4458 has a counter-rotating core.[9]

Metallicity edit

NGC 4458 has a low metal content but has an overabundance of the element iron.[9]
