Scientific paper

AGN feedback is a key ingredient in modern galaxy formation models, invoked to suppress star formation (SF) activity in early-type galaxies at recent epochs. However, the physics of this process is not well understood and poorly constrained by observations. Compelling observational evidence for its mere existence has been missing so far. We identified a sample of early-type galaxies in SDSS that define an AGN feedback sequence transitioning from SF via AGN to quiescence. We propose observations on a sub-sample of 18 targets characterizing the AGN feedback process. These data will provide critical information about the presence and significance of black hole activity in this sample, providing deeper insight into the physics of AGN feedback in early-type galaxies.
