Investigating the Properties of the Least Massive Black Holes at the Centers of Active Galaxies
Carol Hood *
Department of Physics and Astronomy, UC Irvine
Central black holes are now ubiquitous in our universe, found in the centers of the majority of galaxies. While decades of observation have suggested a good model of the structures surrounding the black holes, we still don't know how the central black holes initially formed or the physical processes supporting the surrounding structures. Recent advances in technology have produced a surge in the number of known central black holes with masses less than a million solar masses, roughly 100-1000 times less massive than typical central black holes. These low-mass central black holes should provide key details in how central black holes form and grow over cosmic time. I will present new multi-wavelength observations of a sample of central black holes with masses less than a million solar masses in order to examine the structures surrounding these low-mass central black holes and to gain new insight into the growth process of black holes.
