Fourth order indirect integration method for black hole perturbations: even modes
Patxi Ritter, Alessandro D. A. M. Spallicci, Sofiane Aoudia +1
On the basis of a recently proposed strategy of finite element integration in time domain for partial differential equations with a singular source term, we present a fourth order…
Self-force and motion of stars around black holes
A. Spallicci, S. Aoudia
Through detection by low gravitational wave space interferometers, the capture of stars by supermassive black holes will constitute a giant step forward in the understanding of gra…
First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration
Virgo collaboration
We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005. T…
Advanced VIRGO: detector optimization for gravitational waves by inspiralling binaries
Alessandro D. A. M. Spallicci, Sofiane Aoudia, Jose De Freitas Pacheco +2
For future configurations, we study the relation between the abatement of the noise sources and the Signal to Noise Ratio (SNR) for coalescing binaries. Our aim is not the proposit…
Perturbation method in the assessment of radiation reaction in the capture of stars by black holes
Alessandro D. A. M. Spallicci, Sofiane Aoudia
This work deals with the motion of a radially falling star in Schwarzschild geometry and correctly identifies radiation reaction terms by the perturbative method. The results are:…
