Description

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.

Theoretical gamma-ray astrophysics research conducted in the Laboratory for High-Energy Astrophysics concerns astrophysical processes that produce emission at gamma-ray energies. This research attempts to answer fundamental questions such as the origin, structure, and evolution of the Universe; the nature of compact objects; the origin of the cosmic rays; and the structure and evolution of the galaxy. Research is performed on gamma‑ray line and continuum production mechanisms, on physical processes in strong magnetic fields, on the physics of electron‑positron pair plasmas, and on radiation transfer in the gamma‑ray regime.

These physical processes are applied to models of compact sources, including active galactic nuclei, the galactic center, galactic gamma‑ray sources, pulsars, and gamma‑ray bursters. They are also applied to diffuse sources of gamma‑rays, including the galaxy and young supernova remnants. Gamma‑ray tests for the nature of dark matter are also proposed. Applicants are encouraged to participate in the above research or to initiate related projects.

Gamma‑ray tests of special relativity, as well as tests of proposed quantum gravity effects on high energy gamma‑ray processes are also explored.
