Candidate Gravitationally Lensed Dusty Star-forming Galaxies in the
  Herschel Wide Area Surveys
  We present a list of candidate gravitationally lensed dusty star-forming
galaxies (DSFGs) from the HerMES Large Mode Survey (HeLMS) and the Herschel
Stripe 82 Survey (HerS). Together, these partially overlapping surveys cover
372 deg$^{2}$ on the sky. After removing local spiral galaxies and known
radio-loud blazars, our candidate list of lensed DSFGs is composed of 77
sources with 500 $\mu$m flux densities ($S_{500}$) greater than 100 mJy. Such
sources are dusty starburst galaxies similar to the first bright Sub Millimeter
Galaxies (SMGs) discovered with SCUBA. We expect a large fraction of this list
to be strongly lensed, with a small fraction made up of bright SMG-SMG mergers
that appear as Hyper-Luminous Infrared Galaxies (HyLIRGs; $\rm L_{IR}>10^{13}
L_{\odot}$). Thirteen of the 77 candidates have spectroscopic redshifts from CO
spectroscopy with ground-based interferometers, putting them at $z>1$ and well
above the redshift of the foreground lensing galaxies. The surface density of
our sample is 0.21 $\pm$ 0.03 deg$^{-2}$. We present follow-up imaging of a few
of the candidates confirming their lensing nature. The sample presented here is
an ideal tool for higher resolution imaging and spectroscopic observations to
understand detailed properties of starburst phenomena in distant galaxies.
