Ground 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 کاملTeV Gamma Ray Astronomy
The field of ground-based gamma ray astronomy has enjoyed rapid growth in recent years. As an increasing number of sources are detected at TeV energies, the field has matured and become a viable branch of modern astronomy. Lying at the uppermost end of the electromagnetic rainbow, TeV photons are always preciously few in number but carry essential information about the particle acceleration and...
متن کاملGamma-ray Line Astronomy *
Gamma-ray lines from radioactive isotopes, ejected into interstellar space by cosmic nucleosynthesis events, are observed with new space telescopes. The Compton Observatory had provided a sky survey for the isotopes 26 Al, detecting supernova radioactivity and the diffuse glow of long-lived radioactivity from massive stars in the Galaxy. High-resolution spectroscopy is now being exploited with ...
متن کاملGamma Ray Astronomy
This paper summarizes recents results in γ-ray astronomy, most of which were derived with data from groundbased γ-ray detectors. Many of the contributions presented at this conference involve multiwavelength studies which combine ground-based γ-ray measurements with optical data or space-based X-ray and γ-ray measurements. Besides measurements of the diffuse emission from the Galaxy, observatio...
متن کاملImproved energy resolution for VHE gamma-ray astronomy with systems of Cherenkov telescopes
We present analysis techniques to improve the energy resolution of stereoscopic systems of imaging atmospheric Cherenkov telescopes, using the HEGRA telescope system as an example. The techniques include (i) the determination of the height of the shower maximum, which is then taken into account in the energy determination, and (ii) the determination of the location of the shower core with the a...
