Andrea Prestwich was born in Bristol, England in 1962 and has been interested in astronomy since she was about 5 years old. In 1984 she graduated from Queen Mary College, London, with a degree in physics. She completed her PhD in Astrophysics at Imperial College London in 1989, then accepted a post-doctoral position as a NRC Resident Research Associate at NASA-Marshall Space Flight Center. In 1991 she moved to the Smithsonian Astrophysical Observatory where she is a Staff Scientist at the Chandra X-ray Observatory. Andrea lives in Massachusetts with husband Steve Saar (also an astronomer) and twins Christopher and Katie.
Andrea's PhD thesis (with advisor Bob Joseph) was titled "Extra-galactic Infra Red Spectrocopy" and included some of the first measurements of near infrared line emission from external galaxies. Later as a postdoc at NASA-MSFC she worked on low mass star formation in cluster cooling flows.
Since the launch of Chandra, Andrea's research has focussed on understanding X-ray souces in starburst and star forming galaxies. She has worked on X-ray source classification, understanding the relation between X-ray emission and star formation activity and Ultra-Luminous X-ray sources (ULXs). In Chandra Cycle 2 (2000) she was PI on a Large Project to study the discrete X-ray source population in spiral galaxies. More recently, she is PI on Chandra projects to study the X-ray source population in the ring galaxy NGC 922 and search for ULX in Extremely Metal Poor Spiral Galaxies. She is also involved in studies investigating the links between High Mass X-ray Binary formation and star clusters (with collaborators Rupali Chandar and Blagoy Rangelov).
Chandra X-ray Center (CXC) Activities
Andrea works in the Director's Office at the Chandra X-ray Center. She is responsible for maintaining the CXC science website and the CXC HelpDesk. She's also technical editor of Chandra proposal preparation material (e.g. the Proposer's Observatory Guide and sometimes responds to Target of Opportunity requests.
