Gravitational Waves and Black Hole perturbations in Acoustic Analogues
Chiara Coviello, Maria Luisa Chiofalo, Dario Grasso +3
Phonons in Bose-Einstein condensates propagate as massless scalar particles on top of an emergent acoustic metric. This hydrodynamics/gravity analogy can be exploited to realize ac…
Analogue Gravity
Carlos Barcelo, Stefano Liberati, Matt Visser
Analogue gravity is a research programme that explores analogues of general relativistic gravitational fields within other physical systems, particularly but not exclusively in con…
Black Holes Inside and Out 2024: visions for the future of black hole physics
Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27
The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
A novel family of rotating black hole mimickers
Jacopo Mazza, Edgardo Franzin, Stefano Liberati
The recent opening of gravitational wave astronomy has shifted the debate about black hole mimickers from a purely theoretical arena to a phenomenological one. In this respect, mis…
Comment on "Regular evaporating black holes with stable cores"
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +2
Regular black holes are generically unstable because of the classical phenomenon that goes by the name of "mass inflation" which destabilizes the inner horizon. In a recent article…
Fully extremal black holes: a black hole graveyard?
Francesco Di Filippo, Stefano Liberati, Matt Visser
While the standard point of view is that the ultimate endpoint of black hole evolution is determined by Hawking evaporation, there is a growing evidence that classical and semi-cla…
