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…
Black holes in loop quantum gravity: the complete space-time
Rodolfo Gambini, Jorge Pullin
We consider the quantization of the complete extension of the Schwarzschild space-time using spherically symmetric loop quantum gravity. We find an exact solution corresponding to…
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…
Magnetized Neutron Star Mergers and Gravitational Wave Signals
Matthew Anderson, Eric W. Hirschmann, Luis Lehner +5
We investigate the influence of magnetic fields upon the dynamics of and resulting gravitational waves from a binary neutron star merger in full general relativity coupled to ideal…
On the final spin from the coalescence of two black holes
Luciano Rezzolla, Enrico Barausse, Ernst Nils Dorband +4
We provide a compact analytic formula to compute the spin of the black hole produced by the coalescence of two black holes. The expression, which uses an analytic fit of numerical-…
