Discovery of a new TeV gamma-ray source: Ver J0521+211
Archambault, S.; Böttcher, M.; Arlen, T.; Aune, T.; Behera, B. (IOP Science, 2013)We report the detection of a new TeV gamma-ray source, VER J0521+211, based on observations made with the VERITAS imaging atmospheric Cherenkov Telescope Array. These observations were motivated by the discovery of a cluster ... -
Investigating broadband variability of the TeV blazar IES 1959+650
Aliu, E.; Böttcher, M.; Archambault, S.; Arlen, T.; Aune, T. (IOP Publishing, 2014)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 ... -
Long term observations of B2 1215+30 with Veritas
Aliu, E.; Böttcher, M.; Archambault, S.; Arlen, T.; Aune, T. (IOP Science, 2013)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 (VHEs; E > 100 GeV) by VERITAS with a significance of 8.9σ and ... -
Multiwavelength observations and modeling of 1ES 1959+650 in low flux state
Aliu, E.; Böttcher, M.; Archambault, S.; Arlen, T.; Aune, T. (IOP Science, 2013)We report on the VERITAS observations of the high-frequency peaked BL Lac object 1ES 1959+650 in the period 2007–2011. This source is detected at TeV energies by VERITAS at 16.4 standard deviation (σ) significance in 7.6 ... -
Test of models of the cosmic infrared background with multiwavelength observations of the blazar IES 1218+30.4 in 2009
Archambault, S.; Böttcher, M.; Arlen, T.; Aune, T.; Beilicke, M. (IOP Publishing, 2014)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 ... -
Veritas observations of six bright, hard-spectrum Fermi-LAT blazars
Aliu, E.; Böttcher, M.; Archambault, S.; Arlen, T.; Aune, T. (IOP Publishing, 2012)We report on VERITAS very high energy (VHE; E ⩾ 100 GeV) observations of six blazars selected from the Fermi Large Area Telescope First Source Catalog (1FGL). The gamma-ray emission from 1FGL sources was extrapolated up ...
