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 4.4+4.4 −2.2 × 106 M ☉ .[ 7]
One supernova , SN 2020ejm (type Ia , mag. 16), was discovered in IC 2560 on 11 March, 2020.[ 8]
