Approximate Matching of Analytic and Numerical Solutions for Rapidly Rotating Neutron Stars
Emanuele Berti, Nikolaos Stergioulas
We investigate the properties of a closed-form analytic solution recently found by Manko et al. (2000) for the exterior spacetime of rapidly rotating neutron stars. For selected eq…
Gravitational energy loss in high energy particle collisions: ultrarelativistic plunge into a multidimensional black hole
Emanuele Berti, Marco Cavaglia, Leonardo Gualtieri
We investigate the gravitational energy emission of an ultrarelativistic particle radially falling into a D-dimensional black hole. We numerically integrate the equations describin…
Highly damped quasinormal modes of Kerr black holes
Emanuele Berti, Vitor Cardoso, Kostas D. Kokkotas +1
Motivated by recent suggestions that highly damped black hole quasinormal modes (QNM's) may provide a link between classical general relativity and quantum gravity, we present an e…
Asymptotic quasinormal modes of Reissner-Nordström and Kerr black holes
Emanuele Berti, Kostas D. Kokkotas
According to a recent proposal, the so-called Barbero-Immirzi parameter of Loop Quantum Gravity can be fixed, using Bohr's correspondence principle, from a knowledge of highly-damp…
