Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope
D. Horan, R. W. Atkins, H. M. Badran +56
Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE compon…
The First VERITAS Telescope
J. Holder, R. W. Atkins, H. M. Badran +73
The first atmospheric Cherenkov telescope of VERITAS (the Very Energetic Radiation Imaging Telescope Array System) has been in operation since February 2005. We present here a tech…
Multiwavelength Observations of 1ES 1959+650, One Year After the Strong Outburst of 2002
K. Gutierrez, H. M. Badran, S. M. Bradbury +33
In April-May 2003, the blazar 1ES 1959+650 showed an increased level of X-ray activity. This prompted a multiwavelength observation campaign with the Whipple 10 m gamma-ray telesco…
TeV Gamma-Ray Observations of the Perseus and Abell 2029 Galaxy Clusters
J. S. Perkins, H. M. Badran, G. Blaylock +41
Galaxy clusters might be sources of TeV gamma rays emitted by high-energy protons and electrons accelerated by large scale structure formation shocks, galactic winds, or active gal…
Multiwavelength Observations of the Blazar Mrk 421 in December 2002 and January 2003
P. Rebillot, M. Aller, H. Aller +5
We report on a multiwavelength campaign on the TeV gamma-ray blazar Markarian (Mrk) 421 performed during December 2002 and January 2003. These target of opportunity observations we…
A Very High Energy Gamma-Ray Spectrum of 1ES 2344+514
M. Schroedter, H. M. Badran, J. H. Buckley +26
The BL Lacertae (BL Lac) object 1ES 2344+514 (1ES 2344), at a redshift of 0.044, was discovered as a source of very high energy (VHE) gamma rays by the Whipple Collaboration in 199…
