Examples of strong lensing systems imaged in the DES science verification (SV) data. Previously known strongly lensed, bluish-colored arcs are visible in the DES images of three rich galaxy clusters. Top row, from left: Bullet Cluster, RXC J2248.7-4431 and El Gordo. A nearly complete Einstein ring is visible in another cluster lensing system (bottom left), which was previously found by Fermilab scientists. Finally, two new candidate systems discovered in the DES SV data are also shown: one with a giant…
