High-overtone fits to numerical relativity ringdowns: beyond the dismissed n=8 special tone
Xisco Jiménez Forteza, Pierre Mourier
In general relativity, the remnant object originating from an uncharged black hole merger is a Kerr black hole. The approach to this final state is reached through the emission of…
Quasinormal modes and their overtones at the common horizon in a binary black hole merger
Pierre Mourier, Xisco Jiménez Forteza, Daniel Pook-Kolb +2
It is expected that all astrophysical black holes in equilibrium are well described by the Kerr solution. Moreover, any black hole far away from equilibrium, such as one initially…
On average properties of inhomogeneous fluids in general relativity III: general fluid cosmologies
Thomas Buchert, Pierre Mourier, Xavier Roy
We investigate effective equations governing the volume expansion of spatially averaged portions of inhomogeneous cosmologies in spacetimes filled with an arbitrary fluid. This wor…
On the covariance of scalar averaging and backreaction in relativistic inhomogeneous cosmology
Asta Heinesen, Pierre Mourier, Thomas Buchert
We introduce a generalization of the 4-dimensional averaging window function of Gasperini, Marozzi and Veneziano (2010) that may prove useful for a number of applications. The cova…
Lagrangian theory of structure formation in relativistic cosmology. V. Irrotational fluids
Yong-Zhuang Li, Pierre Mourier, Thomas Buchert +1
We extend the general relativistic Lagrangian perturbation theory, recently developed for the formation of cosmic structures in a dust continuum, to the case of model universes con…
Cosmological backreaction and its dependence on spacetime foliation
Thomas Buchert, Pierre Mourier, Xavier Roy
The subject of cosmological backreaction in General Relativity is often approached by coordinate-dependent and metric-based analyses. We present in this letter an averaging formali…
