« Supermassive Black Holes in Nearby Galaxies »

Ralf Bender

Adaptive optics-assisted integraI-field spectroscopy at the VLT has allowed to search for supermassive black holes in hitherto inaccessible nearby galaxies. In this way, we could detect supermassive black holes in dust-enshrouded centers of late-type spiral galaxies and in recent galaxy mergers. Based on the new data and improved catalogs of previous measurements, I will review the correlations between Supermassive Black Holes and their host galaxies and discuss potential physical origins of intrinsic scatter. I will show that supermassive black holes do not correlate with disks or pseudo-bulges, neither do they depend on dark halo properties, in particular the halo circular velocity. Dissipation and baryonic physics during bulge formation seem to be the determining factors in black hole growth.
