Abstract (from CDS):

We report the observation and confirmation of the first group- and cluster-scale strong gravitational lensing systems found in Dark Energy Survey data. Through visual inspection of data from the Science Verification season, we identified 53 candidate systems. We then obtained spectroscopic follow-up of 21 candidates using the Gemini Multi-object Spectrograph at the Gemini South telescope and the Inamori-Magellan Areal Camera and Spectrograph at the Magellan/Baade telescope. With this follow-up, we confirmed six candidates as gravitational lenses: three of the systems are newly discovered, and the remaining three were previously known. Of the 21 observed candidates, the remaining 15 either were not detected in spectroscopic observations, were observed and did not exhibit continuum emission (or spectral features), or were ruled out as lensing systems. The confirmed sample consists of one group-scale and five galaxy-cluster-scale lenses. The lensed sources range in redshift z ∼ 0.80-3.2 and in i-band surface brightness i_SB ∼ 23-25 mag arcsec^-2 (2'' aperture). For each of the six systems, we estimate the Einstein radius θ_E and the enclosed mass M_enc, which have ranges θ_E ∼ 5''-9'' and M_enc ∼ 8 x 10^12 to 6 x 10^13 M_☉, respectively.
