"A close look at the ultra-massive black hole in NGC 1277"

The most massive black holes in the nearby Universe seem to largely be hosted by massive central cluster galaxies. The ultra-massive black hole in NGC 1277, reported by van den Bosch et al. based on a stellar kinematic measurement, is an extreme outlier in this respect. NGC 1277 is not a central cluster galaxy, but a lenticular galaxy in the Perseus Cluster, at a distance of about 3.8’ from the central cluster galaxy. I will present our recent detection of CO(1-0) emission from NGC 1277 and discuss the BH mass based on constraints derived from the molecular gas kinematics.
