Pascal Fortin
The VERITAS collaboration reports the detection of very-high-energy (VHE) gamma-ray emission from the high-frequency-peaked BL Lac object 1ES 1218+304 located at a redshift of z=0.…
VERITAS Discovery of >200GeV Gamma-ray Emission from the Intermediate-frequency-peaked BL Lac Object W Comae
VERITAS Collaboration, V. A. Acciari, E. Aliu +80
We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed betwe…
VERITAS Observations of the gamma-Ray Binary LS I +61 303
V. A. Acciari, M. Beilicke, G. Blaylock +74
LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycl…
Observation of gamma-ray emission from the galaxy M87 above 250 GeV with VERITAS
V. A. Acciari, M. Beilicke, G. Blaylock +74
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to Te…
Stellar Intensity Interferometry with Air Cherenkov Telescope arrays
S. Le Bohec, M. Daniel, W. J. de Wit +5
The present generation of ground-based Very High Energy (VHE) gamma-ray observatories consist of arrays of up to four large (> 12m diameter) light collectors quite similar to those…
Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope
D. Horan, R. W. Atkins, H. M. Badran +56
Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE compon…
