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.

* Generous support for this talk is provided by the ADVANCE grant, a National Science Foundation (NSF) award at Cal Poly Pomona to increase the number of women faculty in the science, technology, engineering and mathematics (STEM) disciplines and to help further their careers.

Refreshments at 11:00 AM. Seminar begins at 11:10 AM.
