Query: A Very High Energy $\gamma$-Ray Survey towards the Cygnus Region of the
  Galaxy   We present results from deep observations towards the Cygnus region using 300
hours of very-high-energy (VHE) $\gamma$-ray data taken with the VERITAS
Cherenkov telescope array and over seven years of high-energy $\gamma$-ray data
taken with the
  Fermi satellite at an energy above 1 GeV. As the brightest region of diffuse
$\gamma$-ray emission in the northern sky, the Cygnus region provides a
promising area to probe the origins of cosmic rays. We report the
identification of a potential Fermi-LAT counterpart to VER J2031+415 (TeV
J2032+4130), and resolve the extended VHE source VER J2019+368 into two source
candidates (VER J2018+367* and VER J2020+368*) and characterize their energy
spectra. The Fermi-LAT morphology of 3FGL 2021.0+4031e (the Gamma-Cygni
supernova remnant) was examined and a region of enhanced emission coincident
with VER J2019+407 was identified and jointly fit with the VERITAS data. By
modeling 3FGL J2015.6+3709 as two sources, one located at the location of the
pulsar wind nebula CTB 87 and one at the quasar QSO J2015+371, a continuous
spectrum from 1 GeV to 10 TeV was extracted for VER J2016+371 (CTB 87). An
additional 71 locations coincident with Fermi-LAT sources and other potential
objects of interest were tested for VHE $\gamma$-ray emission, with no emission
detected and upper limits on the differential flux placed at an average of 2.3%
of the Crab Nebula ux. We interpret these observations in a multiwavelength
context and present the most detailed $\gamma$-ray view of the region to date.
