Research Abstract |
My research uses X-ray observations as a probe of galaxy formation, a topic that encompasses a wide range of key unresolved astrophysical problems such as the nature and distribution of dark matter in the universe and the ejection of metals into the intergalactic medium. X-ray observations offer a unique window to address these and other aspects of galaxy formation. Of particular relevance to my current research is that X-ray observations provide the only means to study the diffuse hot gas (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. With data being provided by two milestone satellites, the Chandra X-ray Observatory and the X-ray Multi-Mirror Mission (XMM), the field of X-ray astronomy has entered an exciting period of discovery. The focus of my current research is to use the outstanding data from these satellites in conjunction with data from other wavebands to build a unified picture of how galaxies and systems of galaxies assemble and evolve into the structures that we see today. |
