New Paper: Luminosity Function of the Earliest Galaxies

We have just submitted a paper (arXiv) to the Astrophysical Journal Letters on the UV luminosity function of the first galaxies. This paper presents some of the first results from the Renaissance Simulations, which is a trio of physics-rich galaxy formation simulations that focus on the earliest epochs, including the first metal-free (Population III stars), in varying large-scale environments. The main result of this paper is the flattening of the luminosity function above an absolute UV magnitude of -14, corresponding to galaxies with less than one million solar masses of stars and 108 solar masses of total mass. We find this aspect, regardless of environment, however the normalization of the luminosity function can vary by an order of magnitude, depending on how density of the environment.
