Abstract
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.
