Talk

The Sunyaev-Zel'dovich (SZ) effect offers an opportunity to probe the properties of the intracluster plasma in galaxy clusters through its interaction with the cosmic microwave background radiation. I will present the detection of the SZ effect at 870 micrometers in the Bullet Cluster of Galaxies, at redshift 0.3. I will discuss the techniques used to remove background submillimeter...

Talk

I will discuss how to quantify the rareness of extreme galaxy clusters without bias. I will also discuss the use of non- Gaussian halo mass functions deep into the tail of their distributions. In each case I will show how to resolve certain problems that have been pointed out in recent literature.

Talk

A decade ago, high-resolution X-ray spectroscopy of galaxy clusters with XMM-Newton and Chandra led to profound changes in our understanding of physical processes governing the state of the plasma in cluster cores. Within the next few years, the advent of X-ray micro-calorimetry will likely open another new window on the the physics of the intracluster medium. I will review the...
