Universal horizons and black hole spectroscopy in gravitational theories with broken Lorentz symmetry
Abstract The violation of Lorentz invariance (LI) in gravitational theories, which allows superluminal propagations, dramatically alters the causal structure of the spacetime and modifies the notion of black holes (BHs). Instead of metric horizons, now universal horizons (UHs) define the boundaries...
