Observation of markarian 421 in tev gamma rays over a 14-year time span
(Elsevier BV, 2014-02-01)
Test of models of the cosmic infrared background with multiwavelength observations of the blazar 1es 1218+30.4 in 2009
(IOP Publishing, 2014-06-04)
We present the results of a multi-wavelength campaign targeting the blazar 1ES 1218+30.4 with observations with the 1.3 m McGraw-Hill optical telescope, the Rossi X-ray Timing Explorer (RXTE), the Fermi Gamma-Ray Space ...
Very-high energy observations of the galactic center region by veritas in 2010-2012
(IOP Publishing, 2014-07-16)
The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the ...
Deep broadband observations of the distant gamma-ray blazar pks 1424+240
(IOP Publishing, 2014-03-28)
We present deep VERITAS observations of the blazar PKS 1424+240, along with contemporaneous Fermi Large Area Telescope, Swift X-ray Telescope, and Swift UV Optical Telescope data between 2009 February 19 and 2013 June 8. ...
Constraints on very high energy emission from grb 130427a
(IOP Publishing, 2014-10-10)
Prompt emission from the very fluent and nearby (z = 0.34) gamma-ray burst GRB130427A was detected by several orbiting telescopes and by ground-based, wide-field-of-view optical transient monitors. Apart from the intensity ...
Spatially resolving the very high energy emission from mgro j2019+37 with veritas
(IOP Publishing, 2014-05-23)
We present very high energy (VHE) imaging of MGRO J2019+37 obtained with the VERITAS observatory. The bright extended (similar to 2 degrees) unidentified Milagro source is located toward the rich star formation region ...
Observations of the unidentified gamma-ray source tev j2032+4130 by veritas
(IOP Publishing, 2014-02-07)
TeV J2032+4130 was the first unidentified source discovered at very high energies (VHEs; E > 100 GeV), with no obvious counterpart in any other wavelength. It is also the first extended source to be observed in VHE ...
Investigating broadband variability of the tev blazar 1es 1959+650
(IOP Publishing, 2014-12-03)
We summarize broadband observations of the TeV-emitting blazar 1ES 1959+650, including optical R-band observations by the robotic telescopes Super-LOTIS and iTelescope, UV observations by Swift Ultraviolet and Optical ...
A three-year multi-wavelength study of the very-high-energy γ-ray blazar 1es 0229+200
(IOP Publishing, 2014-01-21)
The high-frequency-peaked BL Lacertae object 1ES 0229+200 is a relatively distant (z = 0.1396), hard-spectrum (Gamma similar to 2.5), very-high-energy (VHE; E > 100 GeV) emitting gamma-ray blazar. VHE measurements ...
Investigating the tev morphology of mgro j1908+06 with veritas
(IOP Publishing, 2014-05-15)
We report on deep observations of the extended TeV gamma-ray source MGRO J1908+06 made with the VERITAS very high energy gamma-ray observatory. Previously, the TeV emission has been attributed to the pulsar wind nebula ...
