Abstract : Binary black holes have been in limelight off late due to the detection of gravitational waves from coalescing compact binaries in the events such as GW150914. In wake of this we study gravitational lensing by the binary black holes modeled as equal mass Majumdar-Papapetrou dihole metric and show that this system displays features that are quite unprecedented and absent in any other lensing configuration investigated so far. We unravel the existence of a new set of relativistic images and caustics. We also discuss the implication of our study for gravitational wave science. (Based on Phys. Rev. D 95, 024026 (2017))
