Tracing the growth of the first black holes

Abstract: Massive black holes, weighing millions to billions of solar
masses, powered luminous quasars within the first billion years of the
Universe. The first massive black holes must therefore have formed
around the time the first stars and galaxies formed, at the end of the
cosmic Dark Ages. In this talk I will discuss our recent simulations
that trace the evolution of massive black holes in the first billion
year of the Universe, and review possible strategies for testing our
understanding of this early evolution.
