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...
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...
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...
