My research uses X-ray observations as a probe of galaxy formation and evolution, a topic that encompasses a wide range of astrophysical problems of current interest such as the nature and distribution of dark matter in the Universe and the role of feedback processes in galaxy formation, such as the ejection of metals into the intergalactic medium. The breadth of this problem requires studying phenomena that manifest themselves across the entire electromagnetic spectrum. Of particular relevance to my research is that X-ray observations provide the principal means to study the diffuse hot plasma (T = 10-100 MK) in elliptical galaxies, groups, and clusters of galaxies, which usually extends to larger radii and, in the case of clusters, contains even more baryonic mass than do the stars. X-ray astronomy continues to experience an exciting period of discovery with the successful operations of multiple world-class telescopes.
