GeV-TeV Gamma-ray Astronomy
The history of gamma-ray astronomy began in the 1950’s when Hayakawa [1] and Morrison [2] predicted that gamma-rays would be produced via neutral pion decays generated in collisions of cosmic-rays with interstellar matter. Cherenkov observation of air showers was pioneered by Jelly [3] and Chudakov applied this technique to search for gamma-ray signals from celestial sources [4]. Since this ear...
متن کاملThe Physics Potential of Ground-Based Gamma-Ray Astronomy below 50 GeV
Currently three ground-based Air Cherenkov detectors with energy thresholds below 50 GeV are being commissioned (CELESTE and STACEE) or under construction (MAGIC Telescope). Based on the expected performance of the MAGIC Telescope and with an emphasis on those physics questions which are unique to the energy domain below 50 GeV an overview of the scientific prospects of ground-based high energy...
متن کاملThe MAGIC telescope for gamma-ray astronomy above 30 GeV
The MAGIC telescope is presently at its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the island of La Palma. MAGIC will become the largest ground-based gamma ray telescope in the world, being sensitive to photons of energies as low as 30 GeV. The spectral range between 10 and 300 GeV remains to date mostly unexplored. Observations in this region of the spectrum are exp...
متن کاملGround based gamma-ray astronomy with Cherenkov Telescopes
Very-high-energy (>100 GeV) γ-ray astronomy is emerging as an important discipline in both high energy astrophysics and astro-particle physics. This field is currently dominated by Imaging Atmospheric-Cherenkov Telescopes (IACTs) and arrays of these telescopes. Such arrays have achieved the best angular resolution and energy flux sensitivity in the γ-ray domain and are still far from the fundam...
متن کاملFuture Directions in Ground-Based Gamma-Ray Astronomy
With the recent successes of gamma-ray astronomy an obvious question is raised: where is this field going next? At present we have a network of similar air Cerenkov telescope arrays throughout the world and a large water detector in the USA. Here we try to identify which practical paths exist to newer, more sensitive instruments and what these might hold for the future.
