Introduction to spectral methods
Philippe Grandclement
This proceeding is intended to be a first introduction to spectral methods. It is written around some simple problems that are solved explicitly and in details and that aim at demo…
Relativistic Calculations of Coalescing Binary Neutron Stars
Joshua Faber, Philippe Grandclément, Frederic Rasio
We have designed and tested a new relativistic Lagrangian hydrodynamics code, which treats gravity in the conformally flat approximation to general relativity. We have tested the r…
Searching for Gravitational Waves from the Inspiral of Precessing Binary Systems: Astrophysical Expectations and Detection Efficiency of "Spiky'' Templates
Philippe Grandclement, Mia Ihm, Vassiliki Kalogera +1
Relativistic spin-orbit and spin-spin couplings has been shown to modify the gravitational waveforms expected from inspiraling binaries with a black hole and a neutron star. As a r…
A constrained scheme for Einstein equations based on Dirac gauge and spherical coordinates
S. Bonazzola, E. Gourgoulhon, P. Grandclement +1
We propose a new formulation for 3+1 numerical relativity, based on a constrained scheme and a generalization of Dirac gauge to spherical coordinates. This is made possible thanks…
Searching for Gravitational Waves from the Inspiral of Precessing Binary Systems: New Hierarchical Scheme using "Spiky" Templates
P. Grandclement, V. Kalogera
In a recent investigation of the effects of precession on the anticipated detection of gravitational-wave inspiral signals from compact object binaries with moderate total masses,…
