Detection of TeV Gamma Rays from the BL Lac Object 1ES1959+650 with the Whipple 10m Telescope
J. Holder, VERITAS collaboration
We present the first strong detection of very high energy gamma-rays from the close (z=0.048) X-ray selected BL Lacertae object 1ES1959+650. Observations were made with the Whipple…
The TeV spectrum of H1426+428
D. Petry, I. H. Bond, S. M. Bradbury +45
The BL Lac object H1426+428 was recently detected as a high energy gamma-ray source by the VERITAS collaboration (Horan et al. 2002). We have reanalyzed the 2001 portion of the dat…
Discovery of Spectral Variability of Markarian 421 at TeV Energies
F. Krennrich, I. H. Bond, S. M. Bradbury +38
The detection of spectral variability of the gamma-ray blazar Mrk 421 at TeV energies is reported. Observations with the Whipple Observatory 10m gamma-ray telescope taken in 2000/2…
Search for Neutron-Antineutron Oscillations Using Multiprong Events in Soudan 2
J. Chung
We have searched for neutron-antineutron oscillations using the 5.56 fiducial kiloton-year exposure of the Soudan 2 iron tracking calorimeter. We require candidate n-nbar occurrenc…
The Composition of Cosmic Rays at the Knee
S. P. Swordy, L. F. Fortson, J. Hinton +21
The observation of a small change in spectral slope, or 'knee' in the fluxes of cosmic rays near energies 10^15 eV has caused much speculation since its discovery over 40 years ago…
Detection of the BL Lac Object H1426+428 at TeV Gamma Ray Energies
D. Horan
A very high energy (VHE) gamma-ray signal has been detected at the 5.4 sigma level from H1426+428, an x-ray selected BL Lacertae object at a redshift of 0.129. The object was monit…
