Title: The CO Mapping Array Project and Joint Analyses for LIM
Abstract: Line Intensity Mapping (LIM) is a fast-growing observational technique designed to measure the integrated emission from galaxies as fluctuations in a 3D cosmic volume. This means LIM experiments are sensitive to the emission from all galaxies in a population, even the very faintest, which has wide-reaching applications for both cosmology and galaxy formation. COMAP (the CO Mapping Array Project), is a currently observing LIM experiment targeting dense molecular gas in galaxies via their CO(1-0) emission at redshifts spanning the peak of cosmic star formation to the Epoch of Reionization. COMAP is currently leading the field in constraints on the CO power spectrum at z~3. I will present the current COMAP constraints, and discuss techniques for improving sensitivity while simultaneously exploring the galaxy population in more detail by combining COMAP LIM data with existing spectroscopic surveys of galaxies through multi-tracer analyses, such as stacking and cross-correlation. These tools are a critical part of the COMAP analysis pipeline, and have the potential to be very useful for forthcoming LIM experiments.
