Minimal Stereoscopic Analysis for Imaging Atmospheric Cherenkov Telescope Arrays
The trajectory of a primary γ-ray detected with an array of at least four atmospheric Cherenkov imaging telescopes can be reconstructed from the shower image centroid positions and geometrical considerations independent of the primary energy. Using only the image centroid positions some cosmic-ray discrimination is also possible. This minimal approach opens the possibility of pushing the analys...
متن کاملUsing Atmospheric Cherenkov Telescope arrays as Intensity Interferometers
The Narrabri intensity interferometer was successfully used until 1974 to observe 32 stars [1], all brighter than B=+2.5, among which some were found to have an angular diameter as small as 0.41+/-0.03 milli-arcseconds (mas). The technique was then abandoned in favor of Michelson interferometry [2, 3]. Here we consider the technical feasibility and scientific potential of implementing intensity...
متن کاملA Topological Trigger System for Imaging Atmospheric-Cherenkov Telescopes
A fast trigger system is being designed as a potential upgrade to VERITAS, or as the basis for a future array of imaging atmospheric-Cherenkov telescopes such as AGIS. The scientific goal is a reduction of the energy threshold1by a factor of 2 over the current threshold of VERITAS of around 130 GeV. The trigger is being designed to suppress both accidentals from the night-sky background and cos...
متن کاملThe H.E.S.S. Imaging Atmospheric Cherenkov Telescope Array is currently the most sensitive
The H.E.S.S. Imaging Atmospheric Cherenkov Telescope Array is currently the most sensitive instrument for Very High Energy (VHE) γ-ray observations in the energy range of about 0.1-10 TeV. During more than two years of operation with the complete 4-telescope array, many galactic and extragalactic VHE γ-ray sources have been discovered. With its superior sensitivity and its large field-of-view c...
متن کاملTowards an optimized design for the Cherenkov Telescope Array
The Cherenkov Telescope Array (CTA) is a future instrument for very-high-energy (VHE) gamma-ray astronomy that is expected to deliver an order of magnitude improvement in sensitivity over existing instruments. In order to meet the physics goals of CTA in a cost-effective way, Monte Carlo simulations of the telescope array are used in its design. Specifically, we simulate large arrays comprising...
