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…

Spectrum of Very High Energy Gamma-Rays from the blazar 1ES1959+650 during Flaring Activity in 2002

M. K. Daniel

The blazar 1ES 1959+650 was observed in a flaring state with the Whipple 10 m Imaging Atmospheric Cherenkov Telescope during May of 2002. A spectral analysis has been carried out o…

A Search for TeV Gamma-Ray Emission from High-Peaked Flat Spectrum Radio Quasars Using the Whipple Air-Cherenkov Telescope

A. D. Falcone, the VERITAS collaboration

Blazars have traditionally been separated into two broad categories based upon their optical emission characteristics; BL Lacs, with faint or no emission lines, and flat spectrum r…
