NGC 1271 is a compact elliptical or lenticular galaxy[2] located about 250 million light-years away[3] in the constellation Perseus.[4] The galaxy was discovered by astronomer Guillaume Bigourdan on November 14, 1884.[5] NGC 1271 is a member of the Perseus Cluster[6] and has a nuclear dust disk in its center.[7] It also has an edge-on, intermediate-scale disk and has a central bulge. Like NGC 1277, NGC 1271 is a candidate "relic galaxy".[8]

Supermassive black hole

Using orbital-based stellar dynamical models, Walsh et al. determined that the supermassive black hole in the center of NGC 1271 has a mass of .
