Title: Stellar populations of Brightest Cluster Galaxies
Author(s): Sarah Brough
Abstract:
Hierarchical models suggest that the most massive galaxies must have
assembled their stellar mass most recently.  As some of the most
massive galaxies, Brightest Cluster Galaxies enable a unique test of
galaxy formation models.  I will present my investigations into the
radial stellar population profiles of Brightest Cluster Galaxies, and
how they depend on their cluster environment, using high S/N
Gemini long-slit spectra.  I will discuss what this tells us about
their formation histories, how their formation histories differ from
those of other galaxy populations and what this means for current
models of galaxy evolution.
