Recent studies have suggested that red quasars are a phase in quasarevolution when feedback from black hole accretion evacuates obscuring gas fromthe nucleus of the host galaxy. Here, we report a direct link betweendust-reddening and molecular outflows in quasars at $z\sim2.5$. By examiningthe dynamics of warm molecular gas in the inner region of galaxies, we detectoutflows with velocities 500--1000 km s$^{-1}$ and infer timescales of$\approx0.1$ Myr that are due to ongoing quasar energy output. We observeoutflows only in systems where quasar radiation pressure on dust in thevicinity of the black hole is sufficiently large to expel their obscuring gascolumn densities. This result is in agreement with theoretical models thatpredict radiative feedback regulates gas in the nuclear regions of galaxies andis a major driving mechanism of galactic-scale outflows of cold gas. Ourfindings suggest that radiative quasar feedback ejects star-forming gas fromwithin nascent stellar bulges at velocities comparable to those seen on largerscales, and that molecules survive in outflows even from the most luminousquasars.

Red quasars blow out molecular gas from galaxies during the peak of cosmic star formation
