Perturbative black-hole and horizon solutions in gravity with explicit spacetime-symmetry breaking
Samy Aoulad Lafkih, Nils A. Nilsson, Marie-Christine Angonin +1
In this paper, we present static and spherically symmetric vacuum solutions to the mass-dimension action of an effective-field theory, choosing the diffeomorphism symmetr…

Gravitational-wave generation in the presence of Lorentz invariance violation
Samy Aoulad Lafkih, Marie-Christine Angonin, Christophe Le Poncin-Lafitte +1
We solve the wave equation for gravitational waves emitted by compact objects systems using the Multipolar Post-Minkowskian (MPM) method, and in the presence of Lorentz invariance…
