PGC 2456

PGC 2456 known as KAZ 364 and JO201, is a spiral galaxy located in the constellation of Cetus. It is located 617 million light-years away from the Solar System.^[1] A member of Abell 85, PGC 2456 lies 360 kiloparsecs from the brightest cluster galaxy, Holmberg 15A.^[2]

PGC 2456 contains an active galactic nucleus.^[3] It is a low-excitation radio galaxy,^[4] with a stellar mass of 3.6 x 10¹⁰ M_⊙.^[5]

PGC 2456 is considered a jellyfish galaxy due to the fact the tendrils are seen drifting downwards from its core.^[6][7] It exhibits intensive star formation in its tendrils and is the Ultraviolet-brightest cluster galaxy in Abell 85.^[8][9]

Such jellyfish galaxies are formed when galaxies like PGC 2456, moves through high speeds across the galaxy clusters, causing ram pressure to strip gas. According to studies, researchers estimated PGC 2456 might have lost about 50% of its mass when undergoing ram-pressure stripping.^[10]
