The Black Hole in the Most Massive Ultracompact Dwarf Galaxy M59-UCD3
We examine the internal properties of the most massive ultracompact dwarf galaxy (UCD), M59-UCD3, by combining adaptive optics assisted near-IR integral field spectroscopy from Gemini/NIFS, and Hubble Space Telescope (HST) imaging. We use the multi-band HST imaging to create a mass model that suggests and accounts for the presence of multiple stellar populations and structural components. We combine these mass models with kinematics measurements from Gemini/NIFS to find a best-fit stellardoi:10.3847/1538-4357/aabc57 fatcat:pxo4yfd4z5hmlfihrfiqoq62oe
