Absolute calibration of imaging atmospheric Cherenkov telescopes
N. Shepherd, J. H. Buckley, O. Celik +5
A calibrated laser pulse propagating through the atmosphere produces a flash of Rayleigh scattered light with an intensity that can be calculated very accurately when atmospheric c…
Using ACT arrays as Intensity Interferometers
S. LeBohec, J. Holder
The Narrabri intensity interferometer was successfully used until 1974 to observe 32 stars, all brighter than B=+2.5, among which some were found to have an angular diameter as sma…
Optical SETI with Imaging Cherenkov Telescopes
J. Holder, P. Ashworth, S. LeBohec +2
The idea of searching for optical signals from extraterrestrial civilizations has become increasingly popular over the last five years, with dedicated projects at a number of obser…
A Multi-wavelength View of the TeV Blazar Markarian 421: Correlated Variability, Flaring, and Spectral Evolution
M. Blazejowski
We report results from a multi-wavelength monitoring campaign on Mrk 421 over the period of 2003-2004. The source was observed simultaneously at TeV and X-ray energies, with suppor…
SGARFACE: A Novel Detector For Microsecond Gamma Ray Bursts
S. LeBohec, F. Krennrich, G. Sleege
The Short GAmma Ray Front Air Cherenkov Experiment (SGARFACE) is operated at the Whipple Observatory utilizing the Whipple 10m gamma-ray telescope. SGARFACE is sensitive to gamma-r…
