Light deflection in the gravimagnetic dipole spacetime
Clémentine Dassy, Jan Govaerts
The gravimagnetic dipole is an asymptotically flat, stationary, axisymmetric vacuum solution to Einstein's General Relativity describing two non-extreme black holes with equal mass…

Velocity rotation curves in the gravimagnetic dipole spacetime
Clémentine Dassy, Jan Govaerts
The gravimagnetic dipole spacetime consists of two counter-rotating black holes of equal mass connected by a Misner string. For a particular distance in between them, the string is…

Deformed Hopfion-Rañada Knots in ModMax Electrodynamics
Clémentine Dassy, Jan Govaerts
Source-free so-called ModMax theories of nonlinear electrodynamics in the four dimensional Minkowski spacetime vacuum are the only possible continuous deformations -- and as a func…
