How far away is far enough for extracting numerical waveforms, and how much do they depend on the extraction method?
Enrique Pazos, Ernst Nils Dorband, Alessandro Nagar +3
We present a method for extracting gravitational waves from numerical spacetimes which generalizes and refines one of the standard methods based on the Regge--Wheeler--Zerilli pert…
Binary black hole merger waveforms in the extreme mass ratio limit
Thibault Damour, Alessandro Nagar
We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses and in the extreme mass ratio limit $m_1m_2\ll (m_…
Binary black hole merger in the extreme mass ratio limit
Alessandro Nagar, Thibault Damour, Angelo Tartaglia
We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses and in the extreme mass ratio limit $m_1m_2\ll (m_…
On the accretion-induced QNM excitation of a Schwarzschild black hole
Alessandro Nagar, Olindo Zanotti, Jose A. Font +1
By combining the numerical solution of the nonlinear hydrodynamics equations with the solution of the linear inhomogeneous Zerilli-Moncrief and Regge-Wheeler equations we investiga…
Numerical analysis of backreaction in acoustic black holes
Roberto Balbinot, Alessandro Fabbri, Serena Fagnocchi +1
Using methods of Quantum Field Theory in curved spacetime, the first order in hbar quantum corrections to the motion of a fluid in an acoustic black hole configuration are numerica…
