Colliding black holes from a null point of view: the close limit
Sascha Husa, Manuela Campanelli, Roberto Gomez +2
We present a characteristic algorithm for computing the perturbations of a Schwarzschild spacetime by means of solving the Teukolsky equations. Our methods and results are expected…
Initial data for two Kerr-like black holes
Sergio Dain
We prove the existence of a family of initial data for the Einstein vacuum equation which can be interpreted as the data for two Kerr-like black holes in arbitrary location and wit…
Searching for continuous gravitational wave sources in binary systems
Sanjeev V. Dhurandhar, Alberto Vecchio
We consider the problem of searching for continuous gravitational wave sources orbiting a companion object. This issue is of particular interest because the LMXB's, and among them…
Binary black holes coalescence: transition from adiabatic inspiral to plunge
Alessandra Buonanno, Thibault Damour
Using two recent techniques giving non-perturbative re-summed estimates of the damping and of the conservative part of the dynamics of two-body systems, we describe the transition…
Searching for continuous gravitational wave signals: the hierarchical Hough transform algorithm
M. A. Papa, B. F. Schutz, A. M. Sintes
It is well known that matched filtering techniques cannot be applied for searching extensive parameter space volumes for continuous gravitational wave signals. This is the reason w…
Numerical Calculation of Conformally Smooth Hyperboloidal Data
Peter Huebner
This is the third paper in a series describing a numerical implementation of the conformal Einstein equation. This paper describes a scheme to calculate (three) dimensional data fo…
