Ann Hornschemeier
Ann Hornschemeier is an American astronomer specializing in X-ray emission from X-ray binary populations. She is the Chief Scientist for the Physics of the Cosmos program at NASA.
Career and research
She chairs the NuSTAR Starburst and Local Group science working group, which observes seven nearby galaxies and uses high-energy X-rays to search for and take pictures of the densest, hottest and most energetic regions in the universe. At NASA, Hornschemeier researches high energy astrophysics and cosmology. She is involved in future research missions, including the ESA Athena mission due to launch in 2028. Hornschemeier is also an adjunct faculty member at Johns Hopkins University.Hornschemeier specializes in studies of x-ray emission from x-ray binary populations, both in the local universe and at cosmologically interesting distances. This work is carried out using surveys by space-based x-ray, UV and infrared observatories, alongside ground-based telescopes. She is also the Chief Scientist for the Physics of the Cosmos programme, NASA's high energy astrophysics and cosmology programme, and is also heavily involved in future missions as a research scientist at NASA, including co-chairing a science panel for the ESA Athena mission due for launch in 2028.
Hornschemeier is heavily involved in future missions, serving as the NASA Deputy Study Scientist for the Laser Interferometer Space Antenna mission, a space-based gravitational wave mission led by the European Space Agency. She works with the Study Scientist and NASA HQ on NASA's scientific and technical contributions to LISA.
