Mapping High-Redshift Star Formation with the CO Mapping Array Project

Line Intensity Mapping is a novel observational technique which offers a new window into astrophysics and cosmology in the high-redshift Universei. I will discuss the results of the second observing season of the CO Mapping Array Project (COMAP), a line intensity mapping experiment seeking to probe the cosmic star formation history by mapping the 115 GHz CO(1-0) emission line at z~3. In its second season, COMAP reported the deepest ever intensity mapping measurement in this wavelength regime. I will show how the early results from COMAP and other intensity mapping measurements may be hinting at excess line emission beyond what is predicted by galaxy formation models, potentially challenging our understanding of high-redshift star formation. I will close by discussing future plans for COMAP and intensity mapping as a whole, including extensions to the Epoch of Reionization and probes of fundamental cosmology.
