Two Updates on Galaxy
Clusters: the Halo Virial Scaling Relation
and Red Sequence Cluster Finding

Departments of Physics and
Abstract. Clusters of galaxies are
attractive to both
cosmologists, who think of them as a
regular family of dark matter
halos, and astrophysicists, who consider
them rare locations where
messy, coupled processes drive baryonic
evolution. This talk will
use two recent projects to illustrate
both viewpoints, ending with
a perspective on how to reconcile them.
