NGC 1271 is a compact elliptical or lenticular galaxy [2] located about 250 million light-years away [4] in the constellation Perseus. [5] The galaxy was discovered by astronomer Guillaume Bigourdan on November 14, 1884. [6] NGC 1271 is a member of the Perseus Cluster [7] [6] and has a nuclear dust disk in its center. [3] It also has an edge-on, intermediate-scale disk and has a central bulge. [2] Like NGC 1277, NGC 1271 is a candidate " relic galaxy". [8]
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 3.0+1.0
−1.1×109
M☉.
