[104.06] Growth of Primordial Black Holes

K. J. Mack, J. P. Ostriker (Princeton University)

We present an analytical study of possible mechanisms for the growth of primordial black holes (PBHs). We estimate the conditions under which PBHs existent at the time of matter-radiation equality could grow to become a cosmologically significant component of dark matter.

Due to velocity perturbations in the accreting matter, we expect a black hole to acquire a Bahcall-Wolf cusp and become "clothed." We explore a variety of dynamical processes that would affect clusters of clothed black holes, which may lead to further accretion and mergers.
