Investigating Broadband Variability Of The Tev Blazar 1es 1959+650, P. T. Reynolds, Veritas Dec 2014

Investigating Broadband Variability Of The Tev Blazar 1es 1959+650, P. T. Reynolds, Veritas

Physical Sciences Publications

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 Telescope, X-ray observations by the Swift X-ray Telescope, high-energy gamma-ray observations with the Fermi Large Area Telescope, and very-high-energy (VHE) gamma-ray observations by VERITAS above 315 GeV, all taken between 2012 April 17 and 2012 June 1 (MJD 56034 and 56079). The contemporaneous variability of the broadband spectral energy distribution is explored in the context of a simple synchrotron self Compton (SSC) model. In the SSC emission scenario, we find that the …


Observations Of The Unidentified Gamma-Ray Source Tev J2032+4130 By Veritas, P. T. Reynolds, Et. Al. Mar 2014

Observations Of The Unidentified Gamma-Ray Source Tev J2032+4130 By Veritas, P. T. Reynolds, Et. Al.

Physical Sciences Publications

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 gamma rays. Following its discovery, intensive observational campaigns have been carried out in all wavelengths in order to understand the nature of the object, which have met with limited success. We report here on a deep observation of TeV J2032+4130 based on 48.2 hr of data taken from 2009 to 2012 by the Very Energetic Radiation Imaging Telescope Array System experiment. The source is …
