Segev Benzvi is an experimental physicist specializing in astroparticle physics, which is the study of cosmic rays, gamma rays, and neutrinos from extraterrestrial sources. His focus is the study of charged cosmic rays and gamma rays above 1 TeV, an energy range that allows us to indirectly observe high-energy particle acceleration in supernovae, active galactic nuclei, and gamma-ray bursts.
At TeV, observations of gamma rays are also very important for cosmology, because the gamma rays with interact with primordial radiation fields (the cosmic infrared background) that are very difficult to observe directly. In addition, TeV gamma rays can be used as possible tracers of dark matter annihilation.
Segev currently participates in the High-Altitude Water Cherenkov Gamma-Ray Observatory (or HAWC) in central Mexico and the IceCube Neutrino Observatory at the South Pole.
