Destruction of molecular gas reservoirs in early-type galaxies by active galactic nucleus feedback

Working along-side first author Schawinski, Kaviraj selected the early-type galaxies that form the basis of this paper, via visual inspection of SDSS images (following the methodology of Kaviraj+07, ApJS, 173, 619). Kaviraj contributed significantly to the interpretation and analysis - specifically, the comparison between the observed gas-depletion rate and that expected from natural depletion via the Schmidt-Kennicutt Law. The paper shows that the gas-depletion rate along a sequence of progressively stronger AGN activity is much higher than the expectations from the Schmidt-Kennicutt Law, which underpins the paper’s conclusion that AGN feedback drives the gas evolution of these systems.
