The SAMI Galaxy Survey: trends in [α/Fe] as a function of morphology and environment
We present a new set of index-based measurements of [alpha/Fe] for a sample of 2093 galaxies in the SAMI Galaxy Survey. Following earlier work, we fit a global relation between [alpha/Fe] and the galaxy velocity dispersion sigma a for red sequence galaxies, [alpha/Fe] = (0.378 +/- 0.009)log(10) (sig...
