Astrophysics: Theoretical Gamma-Ray Astrophysics

About the role

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.
