30TH INTERNATIONAL COSMIC RAY CONFERENCE Future imaging atmospheric telescopes: performance of possible array configura- tions for gamma photons in the GeV-TeV range
نویسندگان
چکیده
The future of ground based gamma ray astronomy lies in large arrays of Imaging Atmospheric Cherenkov Telescopes (IACT) with better capabilities: lower energy threshold, higher sensitivity, better resolution and background rejection. Currently, designs for the next generation of IACT arrays are being explored by various groups. We have studied possible configurations with a large number of telescopes of various sizes. Here, we present the precision of source, shower core and energy reconstruction for gamma rays in the GeV-TeV range for different altitudes of observation. These results were obtained through tools that we have developed in order to simulate any type of IACT configuration and evaluate its performance.

30TH INTERNATIONAL COSMIC RAY CONFERENCE VERITAS: Status and Latest Results
VERITAS is an atmospheric Cherenkov telescope array designed to study astrophysical sources of very-high-energy gamma radiation. Located in southern Arizona, USA, the array consists of four 12 m-diameter imaging Cherenkov telescopes. All four telescopes have been deployed at the basecamp of the Whipple Observatory and began full operation in early 2007. This paper describes the operational stat...

VERITAS, the Very Energetic Radiation Telescope Imaging Array System, is an array of four imaging Atmospheric Cherenkov telescopes in southern Arizona. It is sensitive to gamma rays at energies above 100GeV. Here, we discuss the results of observations of two well known VHE blazars, Markarian 421 and Markarian 501, during Spring 2006 which were made with the first two telescopes during the comi...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE The performance of an idealized large-area array of moderate-sized IACTs
We present simulations of a large array of imaging atmospheric Cherenkov telescopes (IACTs), for which the size of the array footprint is much larger than the size of the Cherenkov lightpool. To evaluate limitations of the imaging atmospheric Cherenkov technique, the array is simulated under the assumption of ideal optics, having infinite resolution of the photon arrival direction, which makes ...

The high mass X-ray binary LS I +61 303 has been observed over several months in 2006 and 2007 with the VERITAS array of imaging air-Cherenkov telescopes. A signal of high energy gamma rays with energies above 350 GeV is detected in several orbital cycles of the binary system. The detected flux of gamma rays is strongly variable with the orbital period of 26.5 days, while the maximum flux (corr...

Blazars with redshifts z ≤ 0.1 are likely candidates for detection at energies in the range 300 GeV – 50 TeV withČerenkov telescopes and scintillator arrays. We present γ-ray flux predictions for a sample of 15 nearby flat-spectrum radio sources fitting the proton blazar model of Mannheim (1993a) to their observed broad-band spectral energy distributions. At high energies, we use fluxes or flux...
