Search for Pulsed TeV Gamma-ray Emission from the Crab Pulsar
R. W. Lessard, I. H. Bond, S. M. Bradbury +23
We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10 m gamma-ray telescope. The direction of the Crab pulsar was obser…
VLT Spectroscopy of the z=4.11 Radio Galaxy TN J1338-1942
Carlos De Breuck, Wil van Breugel, Dante Minniti +4
We present optical, infrared and radio data of the z=4.11 radio galaxy TN J1338-1942, including an intermediate resolution spectrum obtained with FORS1on the VLT Antu telescope. TN…
Gamma-Ray Bursts and the Origin of Chondrules and Planets
B. McBreen, L. Hanlon
The effect of a nearby -ray burst (GRB) on the preplanetary solar nebula is considered. The intense irradiation by x-rays and -rays would have caused dust balls to become mol…
A Search for Pulsed TeV Gamma Ray Emission from the Crab Pulsar
A. M. Burdett, I. H. Bond, P. J. Boyle +28
We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10m gamma-ray telescope. The direction of the Crab pulsar was observ…
Short-timescale Variability in the Broadband Emission of the Blazars Mkn421 and Mkn501
M. J. Carson, B. McKernan, T. Yaqoob +1
We analyse ASCA x-ray data and Whipple γ-ray data from the blazars Mkn421 and Mkn501 for short-timescale variability. We find no evidence for statistically significant (>3σ) variab…
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…
