CO Mapping Array Pathfinder (COMAP)

The CO Mapping Array Pathfinder (COMAP) will use the technique of line-intensity mapping to look for molecular gas in star-forming galaxies within several billion years of the Big Bang. The initial phase will trace galaxies at redshift 3 via the CO(1-0) line, using a 19-pixel receiver on a 10 m dish at the Owens Valley Radio Observatory. These observations will also contain information on galaxies emitting in CO(2-1) at redshift 7, which will require future phases to extract. The project is a collaboration involving many institutions including Caltech (PI Kieran Cleary), Stanford, JPL, the University of Manchester, the University of Maryland, the University of Miami, the University of Oslo, the University of Toronto, and ETH Zurich.
