Light deflection in the gravimagnetic dipole spacetime
Abstract
The gravimagnetic dipole is an asymptotically flat, stationary, axisymmetric vacuum solution to Einstein's General Relativity describing two non-extreme black holes with equal masses and opposite NUT charges connected by a Misner string. The string tension's can be set to zero by choosing the black hole separation accordingly, yielding a stable system of oppositely rotating black holes at a fixed distance. Numerical simulations of massless particle geodesics reveal gravitational lensing effects for extended sources at infinity on the equatorial plane or on the vertical axis.
