Very high energy cosmic gamma radiation : a crucial window on the extreme universe /
Gamma ray astronomy, the branch of high energy astrophysics that studies the sky in energetic [symbol]-ray photons, is destined to play a crucial role in the exploration of nonthermal phenomena in the Universe in their most extreme and violent forms. The great potential of this discipline offers imp...
