Competitive effects between gravitational radiation and mass variation for two-body systems in circular orbits
Baptiste Blachier, Aurélien Barrau, Killian Martineau +1
This work provides, at lower order, general analytical solutions for the orbital separation, merging time, and orbital frequency of binary systems emitting gravitational waves whil…
Impact of generalized holonomy corrections on the cosmological primordial power spectra
Maxime De Sousa, Killian Martineau, Cyril Renevey +1
The propagation of perturbations is studied with generalized holonomy corrections in a fully consistent way, ensuring that the deformed algebra of constraints remains closed. The p…
Detailed analysis of the curvature bounce: background dynamics and imprints in the CMB
Cyril Renevey, Aurélien Barrau, Killian Martineau
If the spatial sections of the Universe are positively curved, extrapolating the inflationary stage backward in time inevitably leads to a classical bounce. This simple scenario, n…
Catastrophic fate of Schwarzschild black holes in a thermal bath
Aurélien Barrau, Killian Martineau, Cyril Renevey
Using the Schwarzschild metric as a rudimentary toy model, we pedagogically revisit the curious prediction that the mass of a classical black hole in a constant temperature thermal…
Cosmological implications of generalized holonomy corrections
Cyril Renevey, Killian Martineau, Aurélien Barrau
Most of the phenomenology of loop quantum gravity in the cosmological sector is based on the so-called holonomy correction to the Hamiltonian constraint. It straightforwardly modif…
The effect of screening mechanisms on black hole binary inspiral waveforms
Cyril Renevey, Ryan McManus, Charles Dalang +1
Scalar-tensor theories leaving significant modifications of gravity at cosmological scales rely on screening mechanisms to recover General Relativity (GR) in high-density regions a…
Closer look at white hole remnants
Aurélien Barrau, Léonard Ferdinand, Killian Martineau +1
The idea that, after their evaporation, Planck-mass black holes might tunnel into metastable white holes has recently been intensively studied. Those relics have been considered as…
The string theory swampland in the Euclid, SKA and Vera Rubin observatory era
Aurélien Barrau, Cyril Renevey, Killian Martineau
This article aims at drawing the attention of astronomers on the ability of future cosmological surveys to put constraints on string theory. The fact that "quantum gravity" might b…
Curvature bounce in general relativity: background and primordial spectrum
Cyril Renevey, Aurélien Barrau, Killian Martineau +1
Recent data suggest that the Universe could be positively curved. Combined with an inflationary stage, this might lead to a curvature bounce instead of the Big Bang. The background…
Parameterised post-Newtonian formalism for the effective field theory of dark energy via screened reconstructed Horndeski theories
Cyril Renevey, Joe Kennedy, Lucas Lombriser
We bring together two popular formalisms which generically parameterise deviations from General Relativity on astrophysical and cosmological scales, namely the parameterised post-N…
Review on tests of General Relativity And Modified Gravity Using Pulsar Timing
Cyril Renevey
In this review we aim to describe the most stringent tests of the strong equivalence principle, the fundamental principle of General Relativity, using pulsar timing. For this purpo…
