Closed trapping horizons without singularity
Pierre Binétruy, Alexis Helou, Frédéric Lamy
In gravitational collapse leading to black hole formation, trapping horizons typically develop inside the contracting matter. Classically, an ingoing trapping horizon moves towards…
Polymer Schwarzschild black hole: An effective metric
Jibril Ben Achour, Frédéric Lamy, Hongguang Liu +1
We consider the modified Einstein equations obtained in the framework of effective spherically symmetric polymer models inspired by Loop Quantum Gravity. When one takes into accoun…
Imaging a non-singular rotating black hole at the center of the Galaxy
Frédéric Lamy, Eric Gourgoulhon, Thibaut Paumard +1
We show that the rotating generalization of Hayward's non-singular black hole previously studied in the literature is geodesically incomplete, and that its straightforward extensio…
Non-singular black holes and the Limiting Curvature Mechanism: A Hamiltonian perspective
Jibril Ben Achour, Frederic Lamy, Hongguang Liu +1
We revisit the non-singular black hole solution in (extended) mimetic gravity with a limiting curvature from a Hamiltonian point of view. We introduce a parameterization of the pha…
