Evidence for Intermediate-Age Stellar Populations in Early-Type Galaxies from K-Band Spectroscopy
The study of stellar populations in early-type galaxies in different environments is a powerful tool for constraining their star formation histories. This study has been traditionally restricted to the optical range, where dwarfs around the turn-off and stars at the base of the red giant branch dominate the integrated light at all ages. The near
