The VERITAS Survey of the Cygnus Region of the Galaxy
Abstract
VERITAS (Very Energetic Radiation Imaging Telescope Array System) is an array of four 12 m diameter Imaging Atmospheric Cherenkov Telescopes (IACTs) located at Mt Hopkins, AZ. From 2007 to 2009 VERITAS undertook an extensive survey of the Cygnus region from 67 to 82 degrees Galactic longitude and from -1 to 4 degrees in Galactic latitude. This is a region with many promising Very High Energy (VHE) gamma-ray candidates such as supernova remnants, pulsar wind nebulae, high mass X-ray binaries and massive star clusters including previously detected VHE gamma-ray sources and dozens of GeV gamma-ray sources (detected by the Fermi-LAT). Along with the initial 140 hours of observations, there are over 150 hrs (a total of 294 hours after cuts for bad weather) of follow-up pointed VERITAS observations in the region that we are analyzing with updated analysis techniques. Here we present the current status of this analysis, and of an analysis of over five years of Fermi-LAT data in the region. Using a cross correlation of these results we can motivate continued observations in this active region of the Galaxy, and will incorporate multi-wavelength perspectives into a future results paper.
