Abstract

Faint high-redshift galaxies in the early universe provide constraints on the properties of dark matter, the sources of early ionization, and the details of reionization itself. However, the faint end of the luminosity function has been poorly constrained observationally due to the intrinsic faintness of these objects. JWST is now making it possible to study them: I will present results from the GLIMPSE survey on this population of galaxies.
