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…
The Vlasov-Poisson system with radiation damping
Markus Kunze, Alan D. Rendall
We set up and analyze a model of radiation damping within the framework of continuum mechanics, inspired by a model of post-Newtonian hydrodynamics due to Blanchet, Damour and Scha…
Branes on Group Manifolds, Gluon Condensates, and twisted K-theory
Stefan Fredenhagen, Volker Schomerus
In this work we study the dynamics of branes on group manifolds G deep in the stringy regime. After giving a brief overview of the various branes that can be constructed within the…
Tachyon condensation and universality of DBI action
G. Arutyunov, S. Frolov, S. Theisen +1
We show that a low-energy action for massless fluctuations around a tachyonic soliton background representing a codimension one D-brane coincides with the Dirac-Born-Infeld action.…
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…
The close limit from a null point of view: the advanced solution
Manuela Campanelli, Roberto Gomez, Sascha Husa +2
We present a characteristic algorithm for computing the perturbation of a Schwarzschild spacetime by means of solving the Teukolsky equation. We implement the algorithm as a charac…
Signature Change on the Brane
Marc Mars, Jose M. M. Senovilla, Raul Vera
We explore the possibility of having a good description of classical signature change in the brane scenario.
Classification of image distortions in terms of Petrov types
Thoralf Chrobok, Volker Perlick
An observer surrounded by sufficiently small spherical light sources at a fixed distance will see a pattern of elliptical images distributed over the sky, owing to the distortion e…
Hidden Symmetries, Central Charges and All That
Bernard de Wit, Hermann Nicolai
In this review we discuss hidden symmetries of toroidal compactifications of eleven-dimensional supergravity. We recall alternative versions of this theory which exhibit traces of…
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…
Discrete Lorentzian Quantum Gravity
R. Loll
Just as for non-abelian gauge theories at strong coupling, discrete lattice methods are a natural tool in the study of non-perturbative quantum gravity. They have to reflect the fa…
Search for Periodic Gravitational Wave Sources with the Explorer Detector
P. Astone
We have developped a procedure for the search of periodic signals in the data of gravitational wave detectors. We report here the analysis of one year of data from the resonant det…
Computer Simulations of 3d Lorentzian Quantum Gravity
J. Ambjorn, J. Jurkiewicz, R. Loll
We investigate the phase diagram of non-perturbative three-dimensional Lorentzian quantum gravity with the help of Monte Carlo simulations. The system has a first-order phase trans…
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…
An overview of new supersymmetric gauge theories with 2-form gauge potentials
Friedemann Brandt
An overview of new 4d supersymmetric gauge theories with 2-form gauge potentials constructed by various authors during the past five years is given. The key role of three particula…
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…
Non-perturbative 3d Lorentzian Quantum Gravity
J. Ambjorn, J. Jurkiewicz, R. Loll
We have recently introduced a discrete model of Lorentzian quantum gravity, given as a regularized non-perturbative state sum over simplicial Lorentzian space-times, each possessin…
On the Probability of Microlensing in GRB Afterglows
L. V. E. Koopmans, J. Wambsganss
The declining lightcurve of the optical afterglow of gamma-ray burst GRB000301C showed rapid variability with one particularly bright feature at about t-t0=3.8 days. This event was…
From Now to Timelike Infinity on a Finite Grid
Peter Huebner
We use the conformal approach to numerical relativity to evolve hyperboloidal gravitational wave data without any symmetry assumptions. Although our grid is finite in space and tim…
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…
From ADM to Brane-World charges
Sebastian Silva
We first recall a covariant formalism used to compute conserved charges in gauge invariant theories. We then study the case of gravity for two different boundary conditions, namely…

Archana Pai, Sanjeev Dhurandhar, Sukanta Bose
A data-analysis strategy based on the maximum-likelihood method (MLM) is presented for the detection of gravitational waves from inspiraling compact binaries with a network of lase…
Statistical Physics Approach to M-theory Integrals
Werner Krauth, Matthias Staudacher
We explain the concepts of computational statistical physics which have proven very helpful in the study of Yang-Mills integrals, an ubiquitous new class of matrix models. Issues t…
