Why is a Cluster of Galaxies like a Supernova?
University of Michigan
This talk will review the status of using clusters of galaxies as tools
to study the expansion history and gravitational development of structure
in the universe. After a short historical introduction, I'll discuss
theoretical and computational efforts to understand the cluster population
from first principles. Although successful in many respects, these efforts
are presently challenged to construct a framework for cluster statistics
that will enable high-precision tests of dark matter and dark energy. In
the spirit of the next American administration, I'll discuss what the
field is doing to meet those challenges, particularly as we prepare for
the next generation of multi-wavelength cluster sample from surveys such
as South Pole Telescope, Dark Energy Survey, eRosita and others.
