The Detection of a Population of Submillimeter-Bright, Strongly-Lensed
  Galaxies
  Gravitational lensing is a powerful astrophysical and cosmological probe and
is particularly valuable at submillimeter wavelengths for the study of the
statistical and individual properties of dusty starforming galaxies. However
the identification of gravitational lenses is often time-intensive, involving
the sifting of large volumes of imaging or spectroscopic data to find few
candidates. We used early data from the Herschel Astrophysical Terahertz Large
Area Survey to demonstrate that wide-area submillimeter surveys can simply and
easily detect strong gravitational lensing events, with close to 100%
efficiency.
