The role of morphological quenching in galaxy transformation.

Morphological quenching posits that galaxies might cease star formation based upon galaxy structural properties instead of any dramatic evolutionary processes such as galaxy-galaxy mergers or feedback from an active galactic nucleus. In particular, morphological quenching is invoked to explain the observed lower star formation efficiencies of cold-gas hosting, bulge-dominated galaxies. This talk will summarize the physics behind morphological quenching as well as evidence of morphological quenching of galaxies at both low and high redshift.
