CCAT: Astrophysics in the Next Decade
CCAT is a 25 m diameter submillimeter (200 um - 2.1 mm) telescope to be built at an elevation of 5,600 m, near ALMA. It will have a large field of view (1 square degree) and be instrumented with submillimeter and millimeter cameras and array spectrometers, enabling fast mapping speeds for surveys and optimizing complementarity with ALMA. A substantial fraction of CCAT’s observing time will be devoted to large-scale surveys. Top science priorities include characterizing dusty, star-forming galaxies at high redshifts, investigating the evolution of molecular clouds from their largest scales down to cores, mapping the Sunyaev-Zel’dovich effect in galaxy clusters to probe their evolution, and mapping the interstellar medium in nearby galaxies to probe interactions between the gas, star formation, and nuclear activity. CCAT’s survey capability will provide important
synergies with LSST, ALMA, and JVLA.
