Recent Topics from Very High Energy Gamma-ray Astro- physics
Recent results from very high energy gamma-ray astrophysics are presented. Topics are selected mainly from observations of TeV gamma-rays with atmospheric Cherenkov telescopes covering galactic and extragalactic sources.
متن کاملRecent Status of Very High Energy Gamma Ray Astronomy and Prospects
Gamma-rays, located at the highest energy band of electromagnetic radiation, is directly coupled to the behaviour of energetic particles created and accelerated in the Universe, which are known as cosmic rays. The information on these energetic non-thermal particles, protons in particular, is hard to obtain through other bands. The results of very high energy -rays are summarized by paying a sp...
متن کاملVery High Energy Gamma Ray Astronomy and Cosmic Ray Physics with the ARGO-YBJ experiment
Gamma ray astronomy at energies 1011 1013 eV, which are strictly related to the identification and study of the cosmic ray acceleration sites, is the main scientific goal of the ARGO-YBJ experiment. The detector, which is now being assembled in Tibet (China) at 4300 m a.s.l., is a full coverage Extensive Air Shower array consisting of a carpet of Resistive Plate Chambers covering a surface of a...
متن کاملImaging Very High Energy Gamma-Ray Telescopes
The technique of γ-ray astronomy at very high energies (VHE:> 100 GeV) with ground-based imaging atmospheric Cherenkov telescopes is described, the H.E.S.S. array in Namibia serving as example. Mainly a discussion of the physical principles of the atmospheric Cherenkov technique is given, emphasizing its rapid development during the last decade. The present status is illustrated by two examples...
متن کاملHigh-(Energy)-Lights The Very High Energy Gamma-Ray Sky
The high-lights of ground-based very-high-energy (VHE, E > 100 GeV) gammaray astronomy are reviewed. The summary covers both Galactic and extragalactic sources. Implications for our understanding of the non-thermal Universe are discussed. Identified VHE sources include various types of supernova remnants (shell-type, mixed morphology, composite) including pulsar wind nebulae, and X-ray binary s...
