Fast gravitational waveform models for quasi-circular coalescences of neutron star--black hole binaries
Felip A. Ramis Vidal, Adrian Abac, Marta Colleoni +5
We present IMRPhenomXHM_NSBH and SEOBNRv5HM_ROM_NRTidalv3_NSBH, the first two frequency-domain models for gravitational-wave signals from quasi-circular, aligned-spin neutron star-…
Backreaction and the Role of Spatial Curvature in the Cosmic Neighborhood
Marco Galoppo, Thomas Buchert, Pierre Mourier
We present the first direct computation of spatially averaged dynamical quantities in the local Universe, employing the Cosmicflows-4++ reconstruction and a covariant scalar averag…
Testing Gravity with Binary Black Hole Gravitational Waves
Marta Colleoni, N. V. Krishnendu, Pierre Mourier +2
General Relativity (GR) remains the most accurate theory of gravity to date. It has passed many experimental tests in the Solar System as well as binary pulsar, cosmological and gr…
Splitting the spacetime: A systematic analysis of foliation dependence in cosmic averaging
Pierre Mourier, Asta Heinesen
It is a fundamental unsolved question in general relativity how to unambiguously characterize the effective collective dynamics of an ensemble of fluid elements sourcing the local…
Linear vs. nonlinear modeling of black hole ringdowns
Yi Qiu, Xisco Jiménez Forteza, Pierre Mourier
The ringdown (RD) phase of gravitational waves is of prime interest for testing general relativity (GR). The modelling of the linear quasi-normal modes (QNMs) within the Kerr spect…
Topologically modified Einstein equation: a solution with singularities on
Quentin Vigneron, Áron Szabó, Pierre Mourier
Vigneron [Foundations of Physics, 54, 15, (2024)] recently proposed a modification of general relativity in which a non-dynamical term related to the spatial topology is introduced…
