Innermost stable circular orbit (ISCO) of arbitrary-mass compact binaries with spins at the fourth post-Newtonian order
Luc Blanchet, David Langlois, Etienne Ligout
We compute, up to 4th post-Newtonian (4PN) order, the gauge-invariant stability criterion determining the innermost stable circular orbit (ISCO) for arbitrary-mass compact binaries…
Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order in harmonic coordinates
Luc Blanchet, Guillaume Faye, Emeric Seraille +1
We derive the gravitational radiation-reaction (RR) force in the harmonic coordinate system at the fourth-and-a-half post-Newtonian (4.5PN) order in the case of compact binary syst…
Innermost stable circular orbit of arbitrary-mass compact binaries at fourth post-Newtonian order
Luc Blanchet, David Langlois, Etienne Ligout
We compute by means of post-Newtonian (PN) methods the innermost stable circular orbit (ISCO) of arbitrary-mass (in particular, comparable-mass) compact binaries. Two methods are u…
Comparison of 4.5PN and 2SF gravitational energy fluxes from quasicircular compact binaries
Niels Warburton, Barry Wardell, David Trestini +6
Recent years have seen significant advances in models of gravitational waveforms emitted by quasicircular compact binaries in two regimes: the weak-field, post-Newtonian regime, in…
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…
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 waves 100 years after Einstein
Luc Blanchet
The LIGO-VIRGO collaboration has detected directly on Earth the gravitational wave signals generated by the collision and the merger of two massive black holes at astronomical dist…
