Supermassive Black Hole Mass Estimation Using Molecular Gas Kinematics Observed with Millimeter/Submillimeter Interferometor
Ubiquitely present at the centres of galaxies, supermassive black holes (SMBHs) are key to understand galaxy evolution. However, the SMBH mass-central velocity dispersion relation, which is driving most theoretical efforts, is based on a relatively small number of measurements and only a handful of methods.
Our recent work has shown that it is straightforward to dynamically estimate the mass of SMBHs, by simply probing the near-Keplerian rotation of molecular disks around them at high angular resolution. In the ALMA era, this can yield hundreds of measurements in galaxies of all morphological types.
In the talk, I will show the SMBH mass measurement in NGC 1097 by using ALMA Cycle 0 observation, and also in NGC 3665 by using CARMA observation.
