The centers of dwarf galaxies: from ultra-diffuse to
central black holes.

I will discuss our ongoing efforts to characterize the
lowest-mass supermassive black holes, and the occupation
fraction of black holes in dwarf galaxies. This
distribution has the potential to teach us how the first
supermassive black holes formed. Black holes are
typically found in the most centrally concentrated
galaxies in the universe. At the other extreme, I will
describe our new search for some of the most diffuse
galaxies: ultra-diffuse galaxies, with the mass of
a typical dwarf galaxy spread over the size of
the Milky Way. With the Hyper-Suprime Camera survey we
are able to search for these galaxies in a wide range
of environments, and we are starting to characterize
their specific frequency in halos with a wide range of
mass.
