About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Description: Clusters of Galaxies. The distribution of galaxy clusters as a function of mass and redshift probes the large-scale structure of the Universe and provides competitive constraints on cosmological models. We study X-ray emitting intergalactic medium across mass scales from galaxies to superclusters, including shock fronts and other dynamic phenomena, and the cluster nonthermal components to improve mass estimates. We use X-ray, optical, Sunyaev-Zeldovich and radio data, with X-ray data from Chandra, XMM-Newton, Swift, Suzaku and NuSTAR.

Our lab contributed to Hitomi and XRISM and is developing components for Athena. We also perform high-resolution MHD simulations of clusters to compare with observations and prepare for future X-ray missions.

Active Galaxies: An ongoing program analyzes Chandra, XMM-Newton and NuSTAR AGN data, including broadband spectral fitting, temporal/spectral variations, and the nature of X-ray emission from Seyfert IIs and LINERs, with extensive correlative studies using infrared satellite and Hubble Space Telescope observations.

Diffuse X-Ray Background: The HEAO-1 and ROSAT all-sky databases are used to study high-latitude and unresolved X-ray background emission. Topics include cosmic accretion history, spatial and temporal fluctuations, cross-calibration between observatories, and planning for new missions and observations from sounding rockets, Cube Sats, Explorer and Flagship missions.
