The HEAG is an experimental astrophysics research group at the Space Sciences Laboratory of UC Berkeley and the Center for Astrophysics and Space Sciences at UC San Diego. Our group conducts research using a variety of X-ray, gamma-ray, and cosmic-ray instruments. We utilize existing NASA satellite missions, as well as develop and build state-of-the-art instruments to fly on NASA balloon and satellite missions.

Deeper understanding of our Universe comes from novel experiments to study the physical processes and dynamics in astrophysical sources, and consequently the underlying physical laws that govern their creation and evolution. High energy observations probe extreme environments – the most energetic and exotic objects and locations in our Universe. Our group studies high energy sources on many scales, including cosmic gamma-ray bursts, massive black holes, Galactic supernovae and compact objects, solar flares, and terrestrial electron precipitation. These observations provide insight into physical processes inaccessible in a laboratory. Many of these observations have important implications for fundamental physics. While spanning many orders of magnitude in size and energetics, the high energy processes in these sources are often similar, and hence there is a strong synergy in the instrumentation we build and fly on satellites and balloons to study these various phenomena.
