MG B2016+112: the X-ray light from one of the objects on the left (purple) has been warped by the gravity of the intervening galaxy to produce two beams and X-ray sources (A and B) detected in the Chandra image, which is represented by the dashed square on the right; the X-ray light from the fainter object (blue) produces an X-ray source (C) that has been amplified by the galaxy to be as much as 300 times brighter than it would have been without the lensing; the Chandra image is shown in the inset; these two X-ray-emitting objects are likely a pair of growing supermassive black holes or a growing supermassive black hole and a jet.
