Deflection of Highly Relativistic Particles in a Gravitational Field
C. Barrabes, P. A. Hogan
A novel approach to the calculation of the deflection of highly relativistic test particles in gravitational fields is described. We make use of the light-like boosts of the gravit…
Searching for Gravitational Waves from the Inspiral of Precessing Binary Systems: Astrophysical Expectations and Detection Efficiency of "Spiky'' Templates
Philippe Grandclement, Mia Ihm, Vassiliki Kalogera +1
Relativistic spin-orbit and spin-spin couplings has been shown to modify the gravitational waveforms expected from inspiraling binaries with a black hole and a neutron star. As a r…
Space-time correlations in inflationary spectra, a wave packet analysis
David Campo, Renaud Parentani
The inflationary mechanism of mode amplification predicts that the state of each mode with a given wave vector is correlated to that of its partner mode with the opposite vector. T…
Singular Hypersurfaces in Einstein--Gauss--Bonnet Theory of Gravitation
C. Barrabes, P. A. Hogan
We present a general formalism for describing singular hypersurfaces in the Einstein theory of gravitation with a Gauss--Bonnet term. The junction conditions are given in a form wh…
The Trautman-Bondi mass of initial data sets
P. T. Chrusciel, J. Jezierski, S. Leski
We give a definition of mass for conformally compactifiable initial data sets. The asymptotic conditions are compatible with existence of gravitational radiation, and the compactif…
Cauchy horizons in Gowdy space times
Piotr T. Chruściel, Kayll Lake
We analyse exhaustively the structure of \emph{non-degenerate} Cauchy horizons in Gowdy space-times, and we establish existence of a large class of non-polarized Gowdy space-times…
