Head-on collisions of unequal mass black holes in D=5 dimensions
Helvi Witek, Vitor Cardoso, Leonardo Gualtieri +3
We study head-on collisions of unequal mass black hole binaries in D=5 space-time dimensions, with mass ratios between 1:1 and 1:4. Information about gravitational radiation is ext…
A new approach to the study of quasi-normal modes of rotating stars
V. Ferrari, L. Gualtieri, S. Marassi
We propose a new method to study the quasi-normal modes of rotating relativistic stars. Oscillations are treated as perturbations in the frequency domain of the stationary, axisymm…
Quasi-Normal Modes and Gravitational Wave Astronomy
V. Ferrari, L. Gualtieri
We review the main results obtained in the literature on quasi-normal modes of compact stars and black holes, in the light of recent exciting developments of gravitational wave det…
A hybrid approach to black hole perturbations from extended matter sources
Valeria Ferrari, Leonardo Gualtieri, Luciano Rezzolla
We present a new method for the calculation of black hole perturbations induced by extended sources in which the solution of the nonlinear hydrodynamics equations is coupled to a p…
Coupling of Radial and Axial non-Radial Oscillations of Compact Stars: Gravitational Waves from first-order Differential Rotation
A. Passamonti, M. Bruni, L. Gualtieri +2
We investigate the non-linear coupling between radial and non-radial oscillations of static spherically symmetric neutron stars as a possible mechanism for the generation of gravit…
Perturbative approach to the structure of rapidly rotating neutron stars
Omar Benhar, Valeria Ferrari, Leonardo Gualtieri +1
We construct models of rotating stars using the perturbative approach introduced by J. Hartle in 1967, and a set of equations of state proposed to model hadronic interactions in th…
