CXC Biographies: Ann Hornschemeier
Ph.D. student in Astronomy and Astrophysics at Penn State

Ann Hornschemeier is a 4th year Ph.D. student in Astronomy and Astrophysics at Penn State. She completed her Master's degree in 1999, the topic of which was a 1998 sounding rocket mission to observe Scorpius X-1, the brightest extrasolar X-ray source in the sky. For the past two years, she has been working with Gordon Garmire (PI for ACIS, one of the major instruments on the Chandra X-ray Observatory) and Niel Brandt of Penn State on a very deep Chandra X-ray observation of the Hubble Deep Field-North (HDF-N), one of the most intensively studied patches of sky at all wavelengths.

Ann is a NASA GSRP graduate fellow and a NASA Pennsylvania Space Grant fellow. Ann's main research focus is X-ray astronomy, but she also observes in the optical band. Her current research relies heavily on optical spectroscopy done with the Keck and Hobby-Eberly telescopes. She is also currently working on exciting new prospects for studying "normal" galaxies in the X-ray band at much larger distances than was possible before Chandra.
