The next massive galaxy and quasar frontier at the Cosmic Dawn

Many of the advances in our understanding of cosmic structure have come
from direct computer modeling. In cosmology, we need to develop computer
simulations that cover this vast dynamic range of spatial and time
scales. I will discuss recent progress in cosmological hydrodynamic
simulations of galaxy formation at unprecedented volumes and
resolution. I will focus on predictions for the first quasars and
their host galaxies in the BlueTides simulation.  BlueTides is a
uniquely large volume and high resolution simulation of the high
redshift universe: with 0.7 trillion particles in a volume half a
gigaparsec on a side. This is the first simulation large enough to
resolve the relevant scales for the formation of the first large
galaxies and quasars which will be investigated with the next
generation telescopes (Euclid, JWST and WFIRST).
