We present the analysis of recent high-energy gamma-ray observations of the BL Lac object 1ES 1218+304 with the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE). 1ES 1218+304 is an X-ray bright high-energy peaked BL Lac (HBL) that is …
VERITAS is an array of four, 12-m-diameter, Cherenkov telescopes, designed to explore the very-high-energy gamma-ray sky in the energy band between 100 GeV and 50 TeV. Its construction and commissioning have occurred over the past two years and the …
The EGRET detector on board the Compton Gamma‐Ray Observatory detected pulsed emission from seven pulsars up to energies around 10 GeV. Despite numerous attempts, no pulsed emission has been observed by ground‐based gamma‐ray telescopes operating …
The mirror facets on the VERITAS telescopes, which are of Davies-Cotton design, are aligned in the horizontal stow position using a laser projector at their radius of curvature. The instrument used will be described. The optical support structure is …
Since September 2005, the Whipple 10 m Gamma‐ray Telescope has been used primarily to monitor known TeV AGN. The five Northern Hemisphere blazars that have been previously detected at Whipple, Markarian 421, H1426+428, Markarian 501, 1ES 1959+650 …
VERITAS is a ground-based gamma-ray observatory covering energies between 100 GeV and 50 TeV and will start operating by January 2007. We give a brief report of the construction status and performance characteristics of the telescopes.
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) being constructed in Southern Arizona consists of an array of four Atmospheric Cherenkov 12m Telescopes designed to observe astrophysical gamma rays in the energy range from 100 …
We describe the design and performance of the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) in its complete configuration. STACEE uses the heliostats of a solar energy research facility to collect and focus the Cherenkov photons …
The Crab Nebula is one of the most studied objects in astrophysics with observations extending over the complete detectable range of the electromagnetic spectrum, from radio waves to TeV γ-rays. Its broad spectral energy distribution is unique and …
The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is an atmospheric Cherenkov detector that detects astrophysical gamma rays using the shower-front-sampling technique. STACEE is a fully operational detector utilizing 1 GS/s Flash ADCs …
