Description
The identification of galaxies with overly massive black holes requires two measurements: a black hole mass (Mbh) and a host spheroid mass.Here we provide our measurements for NGC 1277. Our structural decomposition reveals that NGC 1277 is dominated by a classical spheroid with a Sérsic index n = 5.3, a half-light radius, and a stellar mass of 2.7 x 1011 M☉ (using M*/LV = 11.65, Martín-Navarro et al.). Our new kinematical maps obtained from laser guide star assisted, adaptive optics on the Keck I Telescope dramatically reaffirm the presence of the inner, nearly edge-on, disk seen in the galaxy image
