Modelling the final state from binary black-hole coalescences
Luciano Rezzolla
Over the last few years enormous progress has been made in the numerical description of the inspiral and merger of binary black holes. A particular effort has gone into the modelli…
An improved formulation of the relativistic hydrodynamics equations in 2D Cartesian coordinates
Thorsten Kellermann, Luca Baiotti, Bruno Giacomazzo +1
A number of astrophysical scenarios possess and preserve an overall cylindrical symmetry also when undergoing a catastrophic and nonlinear evolution. Exploiting such a symmetry, th…
On the ergoregion instability in rotating gravastars
Cecilia B. M. H. Chirenti, Luciano Rezzolla
The ergoregion instability is known to affect very compact objects that rotate very rapidly and do not possess a horizon. We present here a detailed analysis on the relevance of th…
Accurate evolutions of inspiralling neutron-star binaries: prompt and delayed collapse to black hole
Luca Baiotti, Bruno Giacomazzo, Luciano Rezzolla
Binary neutron-star (BNS) systems represent primary sources for the gravitational-wave (GW) detectors. We present a systematic investigation in full GR of the dynamics and GW emiss…
Constraint-preserving boundary treatment for a harmonic formulation of the Einstein equations
Jennifer Seiler, Bela Szilagyi, Denis Pollney +1
We present a set of well-posed constraint-preserving boundary conditions for a first-order in time, second-order in space, harmonic formulation of the Einstein equations. The bound…
