In this talk we present a physically motivated signal simulation of the most central systematics in the COMAP telescope. While the Season 2 COMAP results provided the strongest constraints on cosmological CO line emission to date, 75% of the data were cut due to systematic errors. Properly understanding, and subsequently mitigating, the systematics are crucial in order to recover the lost...
I will introduce COMAP-Wide, an extension to the ongoing CO Mapping Array Project. Currently, COMAP is operating an autocorrelation-focused CO intensity mapping survey targeting ~12 square degrees of total sky area. COMAP-Wide aims to complement this deep survey with a wide-area, cross-correlation-focused measurement of ~400 square degrees. The primary target of COMAP-Wide will be a...
In this talk, we will present the state-of-the-art COMAP power spectrum methodology, discuss key lessons learned since the COMAP Season 2 release, and mention some advantages of a joint COMAP-Pathfinder and COMAP-Wide analysis. The COMAP power spectrum methodology relies on cross-correlating maps made by specific configurations of detectors and elevations, each with largely independent...
