Gravitationally Lensed Starburst Galaxies

Caption: This shows five of the SPT-discovered sources observed by ALMA and the Hubble Space Telescope (HST). The massive central galaxy (in blue, seen by HST) bends the light from a more distant galaxy that's bright in submillimeter wavelengths, forming a ring-like image of the background galaxy, which is observed by ALMA (red).
