Initial Hubble Diagram Results from the Nearby Supernova Factory
S. Bailey, G. Aldering, P. Antilogus +22
The use of Type Ia supernovae as distance indicators led to the discovery of the accelerating expansion of the universe a decade ago. Now that large second generation surveys have…
Very high energy observations of the BL Lac objects 3C 66A and OJ 287
T. Lindner, D. S. Hanna, J. Kildea +15
Using the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE), we have observed the BL Lac objects 3C 66A and OJ 287. These are members of the class of low-frequency-peake…
The Energy Spectrum of the Blazar Markarian 421 Above 130 GeV
J. E. Carson, J. Kildea, R. A. Ong +15
Markarian 421 (Mrk 421) was the first blazar detected at gamma-ray energies above 300 GeV, and it remains one of only twelve TeV blazars detected to date. TeV gamma-ray measurement…
STACEE Observations of Mrk 421 During the 2001 Flare
STACEE Collaboration, L. M. Boone, D. Bramel +14
STACEE is a ground based gamma-ray observatory that uses a heliostat array, built for solar energy research, to detect atmospheric Cherenkov radiation from gamma-ray initiated exte…
The Status of the STACEE Observatory
C. E. Covault, L. M. Boone, D. Bramel +12
The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is a ground-based instrument designed to study astrophysical sources of gamma radiation in the energy range of 50 t…
Performance of the STACEE Atmospheric Cherenkov Telescope
STACEE Collaboration, D. A. Williams, D. Bhattacharya +20
The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is located at the National Solar Thermal Test Facility of Sandia National Laboratories in Albuquerque, New Mexico,…
