The Black Hole - Bulge Mass Relation in Megamaser Host Galaxies

Ronald Läsker, Jenny E. Greene, Anil Seth +4

We present HST images for nine megamaser disk galaxies with the primary goal of studying photometric BH-galaxy scaling relations. The megamaser disks provide the highest-precision…

Towards Precision Supermassive Black Hole Masses using Megamaser Disks

Remco C. E. van den Bosch, Jenny E. Greene, James A. Braatz +2

Megamaser disks provide the most precise and accurate extragalactic supermassive black hole masses. Here we describe a search for megamasers in nearby galaxies using the Green Bank…
