Imaging 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...
متن کاملVery high-energy gamma rays from gamma-ray bursts.
Very high-energy (VHE) gamma-ray astronomy has undergone a transformation in the last few years, with telescopes of unprecedented sensitivity having greatly expanded the source catalogue. Such progress makes the detection of a gamma-ray burst at the highest energies much more likely than previously. This paper describes the facilities currently operating and their chances for detecting gamma-ra...
متن کاملRecent 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 کاملConstraints on Very High Energy Gamma-ray Emission from Gamma-ray Bursts
The Milagro Gamma-Ray Observatory employs a water Cerenkov detector to observe extensive air showers produced by high-energy particles interacting in the Earth’s atmosphere. Milagro has a wide field of view and high duty cycle, monitoring the northern sky almost continuously in the 100 GeV to 100 TeVenergy range. Milagro is thus uniquely capable of searching for very high energy emission from g...
