NGC 1270 is an elliptical galaxy located about 250 million light-years away[2] in the constellation Perseus.[3] It was discovered by astronomer Heinrich d'Arrest on February 14, 1863.[4] NGC 1270 is a member of the Perseus Cluster[5][4] and has an estimated age of about 11 billion years.[6] However, Greene et al. puts the age of NGC 1270 at about 15.0 ± 0.50 Gy.[7]

NGC 1270 has a supermassive black hole[8] with an estimated mass of no more than 12 billion solar masses (12×109 M☉).[9]

Activity

Spectroscopy of NGC 1270 suggests that the galaxy contains a low-luminosity AGN (LLAGN).[10]

NGC 1275 Group

NGC 1270 is a member of the NGC 1275 group (also known as LGG 88) which has at least 48 members, including NGC 1224, NGC 1267, NGC 1273, NGC 1275, NGC 1277, NGC 1279, IC 288, IC 294, IC 310, and IC 312.[11]
