Gamma rays from the quasar PKS 1441+25: story of an escape
A. U. Abeysekara, S. Archambault, A. Archer +103
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…
VERITAS Collaboration Contributions to the 34th International Cosmic Ray Conference
The VERITAS Collaboration, A. U. Abeysekara, S. Archambault +90
Compilation of papers presented by the VERITAS Collaboration at the 34th International Cosmic Ray Conference (ICRC), held July 30 through August 6, 2015 in The Hague, The Netherlan…
Science Highlights from VERITAS
D. Staszak, A. U. Abeysekara, S. Archambault +88
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is a ground-based array located at the Fred Lawrence Whipple Observatory in southern Arizona and is one of the…
VERITAS detection of -ray flaring activity from the BL Lac object 1ES 1727+502 during bright moonlight observations
S. Archambault, A. Archer, M. Beilicke +80
During moonlit nights, observations with ground-based Cherenkov telescopes at very high energies (VHE, GeV) are constrained since the photomultiplier tubes (PMTs) in the te…
A Directional Gamma-Ray Detector Based on Scintillator Plates
D. Hanna, L. Sagnières, P. Boyle +1
A simple device for determining the azimuthal location of a source of gamma radiation, using ideas from astrophysical gamma-ray burst detection, is described. A compact and robust…
Development of a Compton imager based on bars of scintillator
A. M. L. MacLeod, P. J. Boyle, D. S. Hanna +3
We have developed a compact Compton gamma-ray imager with a large field of view and a low channel-count that is capable of quickly localizing gamma-ray sources in the few hundred k…
