Whipple Observations of BL Lac Objects
M. D'Vali, I. H. Bond, S. M. Bradbury +23
Only BL Lac objects have been detected as extragalactic sources of very high energy (E > 300 GeV) gamma rays. Using the Whipple Observatory Gamma-ray Telescope, we have attempted t…
Hour-Scale Multiwavelength Variability in Markarian 421
M. Catanese, I. H. Bond, S. M. Bradbury +36
Markarian 421 was observed for about four days with BeppoSAX and the Whipple Observatory gamma-ray telescope in April 1998. A pronounced, well-defined, flare with hour-scale variab…
VHE gamma-ray observations of Markarian 501
Whipple Collaboration, A. C. Breslin, I. H. Bond +29
Markarian 501, a nearby (z=0.033) X-ray selected BL Lacertae object, is a well established source of Very High Energy (VHE, E>=300 GeV) gamma rays. Dramatic variability in its gamm…
Search for TeV Gamma-Rays from Shell-Type Supernova Remnants
Whipple Collaboration, R. W. Lessard, I. H. Bond +26
If cosmic rays with energies <100 TeV originate in the galaxy and are accelerated in shock waves in shell-type supernova remnants (SNRs), gamma-rays will be produced as the result…
High-Energy Interactions and Extensive Air Showers
J. Knapp
In this report a summary of recent developments in the fields of high-energy nuclear interactions (HE 1) and air shower phenomenology (HE 2) is presented. New results from accelera…
