The First Galaxies: from HST-WFC3 to Cosmological Simulations
Abstract
Our knowledge of galaxy formation at redshift z>7 has been greatly improved by the new near-IR capabilities of the Hubble Space Telescope. We will present the latest determination of the galaxy luminosity function during the dark ages combining deep WFC3 data to constrain the evolution of the faint end with a large area survey designed to quantify the abundance of bright z>7 galaxies and thus evolution in L_*. The observed luminosity function will be compared to predictions from cosmological simulations of structure formation to assess the contribution of galaxies to the reionization of the Universe.
