Observing AGN Feedback in Action in Early-type Galaxies

Dr. Kevin Schawinski (Yale)

Residual star formation at late times in early-type galaxies and their progenitors must be suppressed in order to explain the population of red, passively evolving systems we see today. Likewise, residual or newly accreted reservoirs of gas that are fuelling star formation must be destroyed. This suppression of star formation in early-type galaxies is now commonly attributed to AGN feedback wherein the reservoir of gas is heated and expelled during a phase of accretion onto the central supermassive black hole. I will outline recent observational work on observing this process in action using data from the Sloan Digital Sky Survey, GALEX and IRAM and how they compare to current models.
