VERITAS Observations of Gamma-Ray Bursts Detected by Swift

VERITAS Collaboration, V. A. Acciari, E. Aliu +84

We present the results of sixteen Swift-triggered GRB follow-up observations taken with the VERITAS telescope array from January, 2007 to June, 2009. The median energy threshold an…

The Track Imaging Cerenkov Experiment

S. A. Wissel, K. Byrum, J. D. Cunningham +10

We describe a dedicated cosmic-ray telescope that explores a new method for detecting Cerenkov radiation from high-energy primary cosmic rays and the large particle air shower they…

Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst

The VERITAS Collaboration, V. A. Acciari, T. Arlen +225

The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
