Talk	Oral abstract	Title	X-ray astrophysics with an X-ray Surveyor mission
Coauthors
Abstract	Over the past 15 years, NASA's Chandra X-ray Observatory has explored the high energy universe with ~half-arcsec angular resolution. Chandra studies have deepened our understanding of topics as diverse as the co-evolution of supermassive black holes and their host galaxies, the investigation of dark energy and dark matter, and the tracing of stellar evolution from star formation to supernova explosions. While there has been tremendous progress, it is also clear that many Chandra observations are photon-limited, leaving us with driving scientific questions which require a high angular resolution successor to Chandra with 1.5-2 orders of magnitude greater collecting area and next generation science instruments. We will discuss the expansion of discovery space and new science topics possible with such an observatory.

Talk	Oral abstract	Title	Chandra observations of the virialization region in Abell 133
Coauthors
Abstract	Detailed observations of the "cosmic melting pot" in the virialization zone of rich galaxy clusters are a new territory for the physics of clusters and the intergalactic medium. The first step has been taken with a deep Chandra study of A133, which has provided a uniquely detailed picture of the Cosmic Web converging onto the cluster virial radius and demonstrated that Chandra can probe to fainter surface brightness levels than any other X-ray observatory now operating. Many of the results from the A133 observation are game-changers for our understanding of the virialization region and its proper modeling.
