Science
CCAT-p is specifically designed to measure the kinematic Sunyaev-Zel’dovich effect of galaxy clusters, to trace the appearance of the first population of star-forming galaxies through intensity mapping of their [CII] emission in the epoch of reionization, and to probe multiple spectral line tracers of the ISM over a range of environments in the Milky Way, Magellanic Clouds and other nearby galaxies. It will also be a next-generation Cosmic Microwave Background observatory.
