Testing regularity of black holes with X-rays and Gravitational Waves
Swarnim Shashank
Physically relevant solutions in general relativity often contain spacetime singularities, which are typically interpreted as a sign of breakdown of the theory at high densities/cu…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Uncovering stochastic gravitational-wave backgrounds with LISA
Quentin Baghi, Nikolaos Karnesis, Jean-Baptiste Bayle +2
Finding a stochastic gravitational-wave background (SGWB) of astrophysical or primordial origin is one of the quests of current and future gravitational-wave observatories. While d…
Gravitational-wave tails of memory at 4PN order
David Trestini, Luc Blanchet
We study a novel cubic nonlinear effect, the tails-of-memory, which consist of a combination of the tail effect (backscattering of linear gravitational waves against the curvature…
Tests of general relativity in the nonlinear regime: a parametrized plunge-merger-ringdown waveform model
Elisa Maggio
Gravitational waves provide a unique opportunity to test gravity in the dynamical and nonlinear regime. We present a parametrized test of general relativity (GR) that introduces ge…
Gravitational waves from compact binaries to the fourth post-Newtonian order
L. Blanchet, G. Faye, Q. Henry +2
The precise knowledge of the gravitational phase evolution of compact binaries is crucial to the data analysis for gravitational waves. Until recently, it was known analytically (f…
Gravitational Wave Flux and Quadrupole Modes from Quasi-Circular Non-Spinning Compact Binaries to the Fourth Post-Newtonian Order
Luc Blanchet, Guillaume Faye, Quentin Henry +2
This article provides the details on the technical derivation of the gravitational waveform and total gravitational-wave energy flux of non-spinning compact binary systems to the 4…
Gravitational-Wave Phasing of Quasi-Circular Compact Binary Systems to the Fourth-and-a-Half post-Newtonian Order
Luc Blanchet, Guillaume Faye, Quentin Henry +2
The inspiral phase of gravitational waves emitted by spinless compact binary systems is derived through the fourth-and-a-half post-Newtonian (4.5PN) order beyond quadrupole radiati…
Multipole expansion of gravitational waves: memory effects and Bondi aspects
Luc Blanchet, Geoffrey Compère, Guillaume Faye +2
In our previous work, we proposed an algorithm to transform the metric of an isolated matter source in the multipolar post-Minkowskian approximation in harmonic (de Donder) gauge t…
