JWST’s GLIMPSE: A view of the faintest galaxies in the first billion years of cosmic time
Abstract
Faint high-redshift galaxies in the early universe constrain the properties of dark matter, the early ionizing sources 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 enabling their study: I will present results from the GLIMPSE survey on this population of galaxies.
