Mechanics of non-Killing horizons
Francesco Del Porro, Jacopo Mazza
We investigate the mechanics of stationary axisymmetric non-Killing horizons, which emerge in spacetimes that do not enjoy the symmetry known as circularity -- as is commonly the c…
Properties of general stationary axisymmetric spacetimes: circularity and beyond
Eugeny Babichev, Jacopo Mazza
We analyse properties of general stationary and axisymmetric spacetimes, with a particular focus on circularity -- an accidental symmetry enjoyed by the Kerr metric, and therefore…
Universal Horizons without Hypersurface Orthogonality
Francesco Del Porro, Stefano Liberati, Jacopo Mazza
A key consequence of Lorentz-violating gravity is the emergence of modified dispersion relations implying the absence of a universal maximum propagation speed. This challenges the…
Towards a Non-singular Paradigm of Black Hole Physics
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18
The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…
