Physics - Astrophysics, Gravitation, and Cosmology Seminar

Observations across multiple domains have shown that black holes are often more massive than can readily be explained.  This includes the black hole mergers observed with LIGO, which challenge canonical stellar synthesis, and the supermassive black holes in the most distant quasars, which are very hard to form via accretion and mergers alone. In this talk I will present results on another domain in which black holes seem to be more massive, and grow faster, than is easily explainable via traditional galaxy assembly pathways – the SMBHs in passively evolving red-sequence elliptical galaxies at z<1.  I will then propose a solution that may help to resolve tensions in b
