The VERITAS survey of the Cygnus region

The Cygnus region is a very active star-forming region of our Galaxy. It has a large number of potential GeV-TeV γ-ray emitters, including many as ten supernova remnants, fourteen pulsars, two high mass X-ray binary systems, and nine OB star associations. Detailed studies of the Cygnus region can give insight into the processes of acceleration and propagation of cosmic-ray particles. The TeV regime of this region was studied using data taken by VERITAS, an array of four 12-meter-diameter imaging atmospheric Cherenkov telescopes located at Mt. Hopkins, Arizona, U.S. From 2007 through 2012, the Cygnus region was observed for about 300 h, covering the area from 67° to 82° in Galactic longitude and from −1° to 4° in Galactic latitude. A complete analysis of the VERITAS data is presented. In addition to various multi-wavelength observations, we also cross-correlate our results, including at least five different gamma-ray sources, with the results of an updated analysis of Fermi-LAT observations.
