Phenomenological aspects of black holes beyond general relativity
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
While singularities are inevitable in the classical theory of general relativity, it is commonly believed that they will not be present when quantum gravity effects are taken into…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
On the viability of regular black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +2
The evaporation of black holes raises a number of conceptual issues, most of them related to the final stages of evaporation, where the interplay between the central singularity an…
Towards a Gordon form of the Kerr spacetime
Stefano Liberati, Giovanni Tricella, Matt Visser
It is not currently known how to put the Kerr spacetime metric into the so-called Gordon form, although the closely related Kerr-Schild form of the Kerr metric is well known. A Gor…
Perturbative treatment of the luminosity distance
Dimitar Ivanov, Stefano Liberati, Matteo Viel +1
We derive a generalized luminosity distance versus redshift relation for a linearly perturbed FLRW (Friedmann-Lemaitre-Robertson-Walker) metric with two scalar mode excitations. We…
Vorticity in analogue spacetimes
Stefano Liberati, Sebastian Schuster, Giovanni Tricella +1
Analogue spacetimes can be used to probe and study physically interesting spacetime geometries by constructing, either theoretically or experimentally, some notion of an effective…
