We present the analysis and results of recent high-energy gamma-ray observations of two low frequency-peaked BL Lac objects, 3C 66A and W Comae, made with Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE). The 3C 66A observations were …
STACEE is an atmospheric Cherenkov telescope using the large mirror area of a solar research facility to obtain a low energy threshold. The telescope has a peak in the detected signal of a power‐law gamma‐ray spectrum near 100 GeV. The low energy …
The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is a ground‐based atmospheric Cherenkov telescope for the detection of very high energy gamma rays from Galactic and extra‐galactic sources. By utilizing the large collection area …
We present here the results of recent observations made with the Whipple 10m imaging Cherenkov telescope of the region of the supernova remnant IC443. No evidence for gamma‐ray emission was found, and we obtain an upper limit above 500 GeV (99.9% …
The prototype for the VERITAS imaging atmospheric Cherenkov telescope array was successfully operated in southern Arizona between September 2003 and April 2004. The prototype consisted of 86 mirror facets mounted centrally on a 12‐meter dish, which …
In observations made with the Whipple 10 m telescope, 1ES 1959+650 (*z* = 0.048) was caught in a high flaring state in May 2002, concurrent with a high X‐ray state, and in June 2002, for which there was no corresponding X‐ray flare. The spectra for …
Gamma‐ray Burst (GRB) observations at Very High Energies (VHE, E 100 GeV) can impose tight constraints on some GRB emission models. Many GRB after‐glow models predict a VHE component similar to that seen in blazars and supernova remnants, in which …
STACEE is an atmospheric Cherenkov detector using the large mirror area of a solar research facility to obtain a low energy threshold. The peak of a detected power law spectrum is around 100 GeV. An exciting possibility for STACEE is to follow up …
We present new results from observations of Active Galactic Nuclei (AGN) by the STACEE experiment. STACEE is a detector for 50-500 GeV gamma rays which uses the array of heliostat mirrors at the National Solar Thermal Test Facility (NSTTF) located …
The search for TeV gamma-ray radiation from starburst galaxies (SBGs) has been conducted by the Whipple 10-m gamma-ray telescope from January 2001 to March 2003. The regions with high star formation rates (SFRs) observed in SBGs are frequently …
