It has become apparent in the past two decades that supermassive black holes (SMBHs) and the galaxies that host them have a symbiotic relationship. The masses of these SMBHs scale with several large-scale galaxy properties, which implies that SMBHs and their host galaxies evolve together, and that their growth is regulated by the feedback from actively feeding SMBHs. These scaling relationships allow insight into galaxy-black hole behavior over cosmic time, therefore it is vital to obtain accurate measurements of the galaxy properties on which these correlations are built.


Dr Justin H. Robinson

Dr Robinson is the assistant professor of astronomy at Troy University, having joined Chemistry and Physics department in August of 2021. He received his BS in physics from Saint Mary's College of California, and his MS in physics and PhD in astronomy from Georgia State University. His work involves measuring properties of galaxies hosting an actively feeding supermassive black hole. Research interests include active galactic nucleus host galaxies, extragalactic distance determinations, galaxy mass determinations, relationships between galaxies and supermassive black holes, and supermassive black hole mass measurement.
