چکیده
There are currently no experiments, either satellite or ground-based, that are sensitive to astro-physical γ-rays in the energy range between 20 and 250 GeV. We are developing the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) to explore this energy range. STACEE will use heliostat mirrors at a solar research facility to collect Cherenkov light in extensive air showers produced by high energy γ-rays. Here we report on the results of on-site test work at the solar facility. We demonstrate that the facility is suitable for use as an astrophysical observatory, and using a full scale prototype of part of STACEE, we detect atmospheric Cherenkov radiation at energies lower than any other experiment to date. Based upon these results we are confident that the eventual STACEE instrument will be capable of exploring the γ-ray sky between 50 and 500 GeV with good sensitivity.

We present the analysis and results of recent high-energy gamma-ray observations of the BL Lac object 3C 66A conducted with the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE). During the 2003-2004 observing season , STACEE extensively observed 3C 66A as part of a multiwavelength campaign on the source. A total of 33.7 hours of data was taken on the source, plus an equivalent-durat...

The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is designed to explore the gamma-ray sky between 20 and 250 GeV using the atmospheric Cherenkov technique. STACEE will use large solar heliostat mirrors to reflect Cherenkov light created in gamma-ray air showers to secondary mirrors on a central tower. The secondary mirrors image this light onto photomultiplier tube cameras that ...

The theory of inertial induction, which has been quite successful in explaining a number of hitherto unexplained astrophysical phenomena, predicts a redshift in light grazing massive objects. The total solar eclipse on 11 August 1999 offers an opportunity of testing the theory. In this paper we predict the additional redshift of a few stars during the eclipse and urge professional astronomers t...
