Detection of TeV Gamma Rays from the BL Lac Object 1ES1959+650 with the Whipple 10m Telescope
J. Holder, VERITAS collaboration
We present the first strong detection of very high energy gamma-rays from the close (z=0.048) X-ray selected BL Lacertae object 1ES1959+650. Observations were made with the Whipple…
Long term observations of B2 1215+30 with VERITAS
VERITAS collaboration, E. Aliu, S. Archambault +82
We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHE; E > 100 GeV) by VER…
Gamma-ray observations of the Be/pulsar binary 1A 0535+262 during a giant X-ray outburst
VERITAS collaboration, V. A. Acciari, E. Aliu +73
Giant X-ray outbursts, with luminosities of about erg s, are observed roughly every 5 years from the nearby Be/pulsar binary 1A 0535+262. In this article, we pres…
Measurement of the extragalactic background light spectral energy distribution with VERITAS
VERITAS collaboration, A. U. Abeysekara, A. Archer +59
The extragalactic background light (EBL), a diffuse photon field in the optical and infrared range, is a record of radiative processes over the Universe's history. Spectral measure…
The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
MAGIC Collaboration, J. AleksiÄ, S. Ansoldi +270
We performed a 4.5-month multi-instrument campaign (from radio to VHE gamma rays) on Mrk421 between January 2009 and June 2009, which included VLBA, F-GAMMA, GASP-WEBT, Swift, RXTE…
VERITAS observations of exceptionally bright TeV flares from LS I +61 303
Anna O'Faolain de Bhroithe, VERITAS collaboration
The very-high-energy (VHE; E > 100 GeV) gamma-ray experiment, VERITAS, detected exceptionally bright flares from the high-mass X-ray binary LS I +61 303 during the period O…
The search for short-term flares in extended VHE Crab Nebula observations with the Whipple 10m telescope
Anna O'Faolain de Bhroithe, VERITAS collaboration
In 1989, the Whipple 10m telescope achieved the first indisputable detection of a TeV gamma-ray source, the Crab Nebula. Until its decommissioning in 2011, the Whipple telescope to…
Multiwavelength observations of a TeV-Flare from W Comae
VERITAS collaboration, V. A. Acciari, E. Aliu +167
We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z=0.102) during a strong outburst of very high energy ga…
