Twenty Years of Discovery with the Chandra X-Ray Observatory: The X-ray Universe in Sharp Focus

The launch of the Chandra X-ray Observatory twenty years ago signified the beginning of a golden age in x-ray astronomy. In this talk I will provide some historical overview and highlight a few of Chandra's great achievements.

David Buote

David Buote received the A.B. Degree in Physics from UC Berkeley (1990), and the S.M. (1992) and Ph.D. (1995) Degrees in Physics from MIT. After a brief postdoctoral stay at MIT, he moved to England to take a Research Associate position at the Institute of Astronomy, Cambridge University in 1996. In 1998 he was awarded one of the inaugural Chandra Postdoctoral Fellowships which he held at Lick Observatory, UC Santa Cruz. Buote joined the faculty in UC Irvine Department of Physics and Astronomy in January, 2001 as an Assistant Professor. He received a Faculty Career Development Award (2003-2004) from UC Irvine which promotes promising young faculty and was promoted to Associate Professor in 2005 and Professor in 2011.
Buote’s research specializes in the use of X-ray observations of elliptical galaxies and galaxy clusters as probes of galaxy evolutionary processes and dark matter content. His research accomplishments include, (1) establishing near-solar iron abundance in the hot interstellar medium (ISM) of the central regions of nearby massive early-type galaxies and galaxy groups, (2) discovering the “Iron Bias” leading to underestimates of ISM iron abundances, (3) establishing the existence and properties of dark matter in nearby massive elliptical galaxies, (4) providing the first precise measurement of the halo concentration-mass relation from galaxy to cluster mass scales broadly consistent with theoretical expectation, and (5) establishing a quantitative relationship between the intracluster medium morphology /dynamical state and the radio luminosity of galaxy cluster radio halos.
In all, Buote has authored and co-authored over 170 publications which have received in total over 4000 citations (h-index 37). He has also been Principal Investigator for numerous observations with X-ray satellites and NASA research grants, served as an ad hoc reviewer for NASA and NSF proposals, served on numerous X-ray telescope time allocation panels, and has refereed numerous papers in the leading astronomical journals. He has served on the HEASARC Users Group Committee, the Nominating Committee for the HEAD Executive Committee, and the ASTRO-H (Hitomi) Science Working Group Selection Committee.

"What's Up?" in this month will be presented by Alex McConahay from RAS
