Organization National Aeronautics and Space Administration (NASA) Reference Code 0208-NPP-NOV26-GSFC-Astrophys Location Goddard Space Flight Center, Greenbelt, Maryland Field of Science Astrophysics Advisors Maurice Andrew Leutenegger, View email address on click.appcast.io, View phone number on click.appcast.io Frederick Scott Porter, View email address on click.appcast.io, View phone number on click.appcast.io Description The NASA Postdoctoral Program (NPP) offers research opportunities to highly talented scientists to engage in ongoing NASA research projects. These fellowships last one to three years. The role involves analysis of data from calorimeter and grating instruments for high‑resolution X‑ray spectroscopic observations of astrophysical objects. The position requires providing high‑quality atomic data through theory development and laboratory benchmark experiments. Tasks include supporting laboratory astrophysics collaborations to provide data for the Chandra, XMM‑Newton, and future XRISM, Athena, Arcus, and Lynx missions; operating high‑resolution X‑ray calorimeter arrays with doped silicon thermistors and transition edge sensors; measuring transition energies, oscillator strengths, and electron‑impact excitation cross sections; archiving and publicizing atomic data; and conducting atomic physics calculations. Responsibilities Analyze data from calorimeter and grating instruments for high‑resolution X‑ray spectroscopy. Develop and benchmark atomic data for astrophysical observations. Operate high‑resolution X‑ray calorimeter arrays at facilities such as LLNL EBIT and SLAC LCLS. Archive and publicize atomic data and model its use in astrophysical studies. Perform atomic physics calculations relevant to mission science. Qualifications Doctoral degree in physics, astronomy, or related field. Experience with X‑ray spectroscopy and atomic data, or related laboratory astrophysics. Strong publication record in relevant areas.
