An overview of quasinormal modes in modified and extended gravity
Flora Moulin, Aurélien Barrau, Killian Martineau
As gravitational waves are now being nearly routinely measured with interferometers, the question of using them to probe new physics becomes increasingly legitimate. In this articl…
Analytical proof of the isospectrality of quasinormal modes for Schwarzschild-de Sitter and Schwarzschild-Anti de Sitter spacetimes
Flora Moulin, Aurélien Barrau
The deep reason why the equations describing axial and polar perturbations of Schwarzschild black holes have the same spectrum is far from trivial. In this article, we revisit the…
Quasinormal modes of black holes in a toy-model for cumulative quantum gravity
Aurélien Barrau, Killian Martineau, Jeremy Martinon +1
The idea that quantum gravity effects might leak outside the horizon of a black hole has recently been intensively considered. In this study, we calculate the quasinormal modes as…
A status report on the phenomenology of black holes in loop quantum gravity: Evaporation, tunneling to white holes, dark matter and gravitational waves
Aurélien Barrau, Killian Martineau, Flora Moulin
The understanding of black holes in loop quantum gravity is becoming increasingly accurate. This review focuses on the possible experimental or observational consequences of the un…
Quantum fields in the background spacetime of a loop quantum gravity black hole
Flora Moulin, Killian Martineau, Julien Grain +1
The description of black holes in loop quantum gravity is a hard and tricky task. In this article, we focus on a minisuperspace approach based on a polymerization procedure. We con…
Scalar spectra of primordial perturbations in loop quantum cosmology
Aurélien Barrau, Pierre Jamet, Killian Martineau +1
This article is devoted to the study of scalar perturbations in loop quantum cosmology. It aims at clarifying the situation with respect to the way initial conditions are set and t…
Fast radio bursts and the stochastic lifetime of black holes in quantum gravity
Aurélien Barrau, Flora Moulin, Killian Martineau
Non-perturbative quantum gravity effects might allow a black-to-white hole transition. We revisit this increasingly popular hypothesis by taking into account the fundamentally rand…
Seeing through the cosmological bounce: Footprints of the contracting phase and luminosity distance in bouncing models
Aurélien Barrau, Killian Martineau, Flora Moulin
The evolution of the luminosity distance in a contracting universe is studied. It is shown that for quite a lot of natural dynamical evolutions, its behavior is far from trivial an…
Some Clarifications on the Duration of Inflation in Loop Quantum Cosmology
Boris Bolliet, Aurélien Barrau, Killian Martineau +1
The prediction of a phase of inflation whose number of e-folds is constrained is an important feature of loop quantum cosmology. This work aims at giving some elementary clarificat…
