A search for brief optical flashes associated with the SETI target KIC 8462852
(IOP Publishing, 2016-02-18)
The F-type star KIC. 8462852 has recently been identified as an exceptional target for search for extraterrestrial intelligence (SETI) observations. We describe an analysis methodology for optical SETI, which we have used ...
A search for pulsations from Geminga above 100 GeV with VERITAS
(American Astronomical Society, 2015-02-10)
We present the results of 71.6 hr of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS between 2007 November and 2013 February were ...
The most powerful flaring activity from the NLSyl PMN J0948+0022
(Oxford University Press, 2015-01-21)
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma-rays, PMN J0948+0022 (z = 0.5846). A y -ray flare was observed by the Large ...
Gamma-rays from the quasar PKS 1441+25: story of an escape
(2015-12-20)
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 detection of significant emission above 100 ...
VERITAS observations of the BL Lac object PG 1553+113
(American Astronomical Society, 2015-01-20)
We present results from VERITAS observations of the BL Lac object PG 1553+113 spanning the years 2010, 2011, and 2012. The time-averaged spectrum, measured between 160 and 560 GeV, is well described by a power law with a ...
VERITAS detection of gamma-ray flaring activity from the BL LAC object 1ES 1727+502 during bright moonlight observations
(American Astronomical Society, 2015-08-01)
During moonlit nights, observations with ground-based Cherenkov telescopes at very high energies (VHEs, E > 100 GeV) are constrained since the photomultiplier tubes (PMTs) in the telescope camera are extremely sensitive ...
Exceptionally bright TEV flares from the binary LS I+61 degrees 303
(IOP Publishing, 2016-01-20)
The TeV binary system LS I +61 degrees 303 is known for its regular, non-thermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ...
The Discovery of gamma-Ray Emission From The Blazar RGB J0710+591
(2010)
The high-frequency-peaked BL Lacertae object RGB J0710+591 was observed in the very high-energy (VHE; E > 100 GeV) wave band by the VERITAS array of atmospheric Cherenkov telescopes. The observations, taken between 2008 ...
VERITAS 2008 - 2009 monitoring of the variable gamma-ray source M87
(2010)
M87 is a nearby radio galaxy that is detected at energies ranging from radio to VHE gamma-rays. Its proximity and its jet, misaligned from our line-of-sight, enable detailed morphological studies and extensive modeling at ...
Discovery of TeV Gamma Ray Emission from Tycho's Supernova Remnant
(2011)
We report the discovery of TeV gamma-ray emission from the Type Ia supernova remnant (SNR) G120.1+1.4, known as Tycho's supernova remnant. Observations performed in the period 2008-2010 with the VERITAS ground-based gamma-ray ...
