Abstract
Current models of galaxy formation require star formation in high-mass
galaxies to be limited by poorly understood mechanisms of quasar feedback.
Feedback processes can be studied by examining the molecular gas content of AGN
hosts through the CO rotational ladder, but the complexity of these
observations means that current data are limited to only extremely CO-bright
objects. Upcoming CO intensity mapping experiments offer an opportunity for a
less biased probe of quasar feedback. By correlating intensity maps with
spectroscopic AGN surveys, we can obtain a measurement of the mean CO
luminosity of a large population of quasars simultaneously. We show that
experiments like COMAP, CCAT-prime, and CONCERTO have enough sensitivity to
detect this cross-correlation if existing AGN observations are representative
of the whole population, and to place interesting upper limits if they are not.
Future surveys will be able to increase the precision of these measurements by
orders of magnitude, allowing detailed studies of quasar properties across a
wide range of cosmic history.
