COSMOS provides the largest sample of HST-resolution imaging data for AGN and their host galaxies. We (Emmy Noether research group at MPIA, Katherine Inskip, Mauricio Cisternas, and Knud Jahnke) continue to probe the properties of AGN host galaxies. We report on our work on the black hole to stellar mass relation of COSMOS AGN and the connection of galaxy merging and AGN activity for COSMOS broad-line AGN.
