"Very High Energy Observations of Satellite-Detected Gamma-Ray Bursts", Taylor Aune (for the VERITAS Collaboration), proceedings of the 2010 Gamma-Ray Burst Conference, Annapolis, MD, USA, November 2010.
Abstract:
Recent results from the Fermi Gamma-ray Space Telescope indicate that gamma-ray bursts (GRBs) are capable of producing photons with energies up to 90 GeV in the rest frame of the burst. The Fermi-LAT may not be sensitive to the highest energy photons associated with GRBs and ground-based, very high energy (VHE) gamma-ray observatories offer the means by which characterization of GRBs from tens of GeV to TeV energies may be accomplished. Milagro and VERITAS are two such observatories and searches for VHE emission from GRBs have been conducted at both during the past decade. Milagro, an extensive air shower array located near Los Alamos, NM was operational from January, 2000 until May, 2008 and during that time obtained data on nearly 140 satellite-detected GRBs. VERITAS, an imaging atmospheric Cherenkov telescope array has been performing follow-up observations of GRBs since mid 2006 and continues to maintain an active GRB observing program. No significant VHE emission from GRBs has been detected by either experiment. Results from both experiments are presented including those from the Milagro observation of the exceptional “naked-eye” burst GRB080319B which place stringent constraints on some models of the burst emission, and the VERITAS observation of GRB080310 which began during the prompt phase of the burst and included a large X-ray flare during the early afterglow.
"Gamma-ray Observations of Blazars with VERITAS and Fermi", Anna Cannon (for the VERITAS Collaboration), proceedings of the 8th INTEGRAL Workshop "The Restless Gamma-Ray Universe", Dublin Castle, Dublin, Ireland, September 2010.
Abstract:
VERITAS (the Very Energetic Radiation Imaging Telescope Array System) is an array of four 12m Imaging Atmospheric Cherenkov Technique (IACT) telescopes, located at the Fred Lawrence Whipple Observatory in Southern Arizona. The array has been fully operational since
September 2007 and the study of blazars is one of the VERITAS collaboration’s key science projects. This paper provides a brief description of both the VERITAS and Fermi Large Area Telescope (Fermi LAT) experiments, an overview of VERITAS’ blazar observations to date, in
conjunction with contemporaneous data from Fermi LAT and other multiwavelength observations where available. Accompanying this is a brief summary of the First Large Area Telescope AGN Catalog and a discussion of recent joint VERITAS-Fermi LAT papers.
"Gamma-ray Observations of Blazars with The Whipple 10M Telescope", Eddie Collins-Hughes (for the VERITAS Collaboration), proceedings of the 8th INTEGRAL Workshop "The Restless Gamma-Ray Universe", Dublin Castle, Dublin, Ireland, September 2010.
Abstract:
This paper presents a status update of the current blazar monitoring campaign with the Whipple 10 m telescope. The configuration and performance characteristics of the telescope are described along with the scientific motivation behind the campaign. A summary of the results obtained from January 2010 to July 2010 on Markarian 421, Markarian 501, 1ES 1218+304 and 1FGL J2001.1+4351 are also reported.
"The VERITAS Survey of the Cygnus Region of the Galactic Plane", John E. Ward (for the VERITAS Collaboration), proceedings of the 8th INTEGRAL Workshop "The Restless Gamma-Ray Universe", Dublin Castle, Dublin, Ireland, September 2010.
Abstract:
VERITAS is an array of imaging atmospheric Cherenkov telescopes, located in southern Arizona, that operates in the 100 GeV to 50 TeV energy range. With VERITAS we have conducted a survey of the Cygnus region of the Galactic plane between 67 < l < 82 and -1 < b < 4 . The Cygnus region was chosen for a blind search due to its high content of potential Very High-Energy (VHE, >100 GeV) gamma-ray sources (including Supernova Remnants, PulsarWind Nebulae, XRay Binaries and stellar OB associations) as well as several previously discovered VHE sources. There are also several high-energy gamma-ray emitters in this region as detected by the Fermi gamma-ray space telescope. The survey has accumulated more than 140 hours of observations and reaches an estimated point-source VHE sensitivity of 4% of the Crab Nebula flux above an energy threshold of 200 GeV. We present details of the survey, analysis, initial results and
follow-up observations.
