'Multi-wavelength Studies of Galaxy Clusters and Their Use as Cosmological Probes'

The availability of extensive optical measurements of member galaxies,
strong and weak gravitational lensing measurements, and resolved X-ray
images, afford detailed determination of the galaxy, gas, and dark matter
spatial profiles. I will describe the results from combined analyses of
high quality multi-wavelength data by implementing a new, largely
model-independent approach. I will then show that the contribution of
clusters to the the X-ray background can be used to set meaningful
constraints on alternative non-Gaussian cosmological models.
