Veritas observations of the bl lac object txs 0506+056
(American Astronomical Society, 2018-07-12)
On 2017 September 22, the IceCube Neutrino Observatory reported the detection of the high-energy neutrino event IC 170922A, of potential astrophysical origin. It was soon determined that the neutrino direction was consistent ...
Erratum: “multi-wavelength observations of the flaring gamma-ray blazar 3c 66a in 2008 october” (2011, apj, 726, 43)
(IOP Publishing, 2011-03-24)
A search for spectral hysteresis and energy-dependent time lags from x-ray and tev gamma-ray observations of mrk 421
(American Astronomical Society, 2016-12-22)
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at different wavelengths, especially in the ...
A luminous and isolated gamma-ray flare from the blazar b2 1215+30
(American Astronomical Society, 2017-02-21)
B2 1215+30 is a BL-Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes and subsequently confirmed by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) ...
A search for brief optical flashes associated with the seti target kic 8462852
(American Astronomical Society, 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 ...
The 2010 very high energy γ-ray flare and 10 years of multi-wavelength observations of m 87
(IOP Publishing, 2012-02-02)
The giant radio galaxy M 87 with its proximity (16 Mpc), famous jet, and very massive black hole ((3-6) x 10(9) M-circle dot) provides a unique opportunity to investigate the origin of very high energy (VHE; E > 100 ...
Discovery of very-high-energy emission from rgb j2243+203 and derivation of its redshift upper limit
(American Astronomical Society, 2017-11-10)
Very-high-energy (VHE; > 100 GeV) gamma-ray emission from the blazar RGB J2243+203 was discovered with the VERITAS Cherenkov telescope array, during the period between 2014 December 21 and 24. The VERITAS energy ...
Search for high‐energy gamma rays from an x‐ray–selected blazar sample
(IOP Publishing, 2003-12-20)
Our understanding of blazars has been greatly increased in recent years by extensive multiwavelength observations, particularly in the radio, X-ray, and gamma-ray regions. Over the past decade the Whipple 10 m telescope ...
Detection of the bl lacertae object h1426+428 at tev gamma‐ray energies
(IOP Publishing, 2002-06-01)
A very high energy gamma-ray signal has been detected at the 5.5sigma level from H1426+ 428, an X-ray-selected BL Lacertae object at a redshift of 0.129. The object was monitored from 1995 to 1998 with the Whipple 10 m ...
The tev spectrum of h1426+428
(IOP Publishing, 2002-11-20)
The BL Lac object H1426+428 was recently detected as a high-energy gamma-ray source by the VERITAS collaboration (Horan et al.). We have reanalyzed the 2001 portion of the data used in the detection in order to examine the ...
