Star Formation in Early-Type Galaxies and the Evolution of the Red Sequence: Insights from Multi-Wavelength Observations
The recently completed SAURON integral field survey has revolutionized our understanding of the internal structure of early-type galaxies. In this talk, I will briefly summarize results from this project and then present insights from the combination of SAURON data with Spitzer mid-IR data, which probes low-level star formation in these "red and dead" galaxies. This wealth of data reveals for the first time the dynamical processes associated with star formation as well as the efficiency of star formation in hostile early-type galaxy environments. Most importantly, the data identify two evolutionary tracks along which early-type galaxies move on and off the red sequence.
