IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift in 1897.[3]
The luminosity class of IC 2560 is II[4] with a broad HI line[5] containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy.[6] It has a distinct bar structure in the center with the supermassive black hole at the core having a mass of .
One supernova, SN 2020ejm (type Ia, mag. 16), was discovered in IC 2560 on 11 March, 2020.[7]
IC 2560 is a member of the NGC 3223 Group. There are 15 other galaxies in the group including NGC 3223, NGC 3224, NGC 3258, NGC 3268, NGC 3289, IC 2552 and IC 2559.[8] Together, the group is part of the Antlia Cluster.[9]
