Compact support of spherically symmetric equilibria in non-relativistic and relativistic galactic dynamics
Gerhard Rein, Alan D. Rendall
Equilibrium states in galactic dynamics can be described as stationary solutions of the Vlasov-Poisson system, which is the non-relativistic case, or of the Vlasov-Einstein system,…
Spin dependent D-brane interactions and scattering amplitudes in matrix theory
J. F. Morales, J. C. Plefka, C. A. Scrucca +2
Spin interactions beteween two moving Dp-branes are analyzed using the Green-Schwarz formalism of boundary states. This approach turns out to be extremely efficient to compute all…
Local Quantum Constraints
Hendrik Grundling, Fernando Lledo
We analyze the situation of a local quantum field theory with constraints, both indexed by the same set of space-time regions. In particular we find ``weak'' Haag-Kastler axioms wh…
Born-Infeld-Goldstone superfield actions for gauge-fixed D-5- and D-3-branes in 6d
Sergei V. Ketov
The supersymmetric Born-Infeld actions describing gauge-fixed D-5- and D-3-branes in ambient six-dimensional (6d) spacetime are constructed in superspace. A new 6d action is the (1…
The exponential law: Monopole detectors, Bogoliubov transformations, and the thermal nature of the Euclidean vacuum in RP^3 de Sitter spacetime
Jorma Louko, Kristin Schleich
We consider scalar field theory on the RP^3 de Sitter spacetime (RP3dS), which is locally isometric to de Sitter space (dS) but has spatial topology RP^3. We compare the Euclidean…
Dynamics of spatially homogeneous solutions of the Einstein-Vlasov equations which are locally rotationally symmetric
A. D. Rendall, K. P. Tod
The dynamics of a class of cosmological models with collisionless matter and four Killing vectors is studied in detail and compared with that of corresponding perfect fluid models.…
Approximate Canonical Quantization for Cosmological Models
Marco Cavaglia
In cosmology minisuperspace models are described by nonlinear time-reparametrization invariant systems with a finite number of degrees of freedom. Often these models are not explic…
Geometrodynamical Formulation of Two-Dimensional Dilaton Gravity
Marco Cavaglia
Two-dimensional matterless dilaton gravity with arbitrary dilatonic potential can be discussed in a unitary way, both in the Lagrangian and canonical frameworks, by introducing sui…
Geometrodynamical Formulation of Two-Dimensional Dilaton Gravity and the Quantum Birkhoff Theorem
Marco Cavaglia
General two-dimensional pure dilaton-gravity can be discussed in a unitary way by introducing suitable field redefinitions. The new fields are directly related to the original spac…
On the Rigidity Theorem for Spacetimes with a Stationary Event Horizon or a Compact Cauchy Horizon
Helmut Friedrich, Istvan Racz, Robert M. Wald
We consider smooth electrovac spacetimes which represent either (A) an asymptotically flat, stationary black hole or (B) a cosmological spacetime with a compact Cauchy horizon rule…
Three Dimensional Numerical General Relativistic Hydrodynamics I: Formulations, Methods, and Code Tests
J. A. Font, M. Miller, W. Suen +1
This is the first in a series of papers on the construction and validation of a three-dimensional code for general relativistic hydrodynamics, and its application to general relati…
Angular momentum near the black hole threshold in scalar field collapse
D. Garfinkle, C. Gundlach, J. M. Martin-Garcia
For the formation of a black hole in the gravitational collapse of a massless scalar field, we calculate a critical exponent that governs the black hole angular momentum for slight…
Second order gauge invariant gravitational perturbations of a Kerr black hole
M. Campanelli, C. O. Lousto
We investigate higher than the first order gravitational perturbations in the Newman-Penrose formalism. Equations for the Weyl scalar representing outgoing gravitational rad…
Cosmic string loops and large-scale structure
P. P. Avelino, E. P. S. Shellard, J. H. P. Wu +1
We investigate the contribution made by small loops from a cosmic string network as seeds for large-scale structure formation. We show that cosmic string loops are highly correlate…
Non-axisymmetric relativistic Bondi-Hoyle accretion onto a Kerr black hole
Jose A. Font, Jose M. Ibanez, Philippos Papadopoulos
In our program of studying numerically the so-called Bondi-Hoyle accretion in the fully relativistic regime, we present here first results concerning the evolution of matter accret…
Human Gravity-Gradient Noise in Interferometric Gravitational-Wave Detectors
Kip S. Thorne, Carolee J. Winstein
Among all forms of routine human activity, the one which produces the strongest gravity-gradient noise in interferometric gravitational-wave detectors (e.g. LIGO) is the beginning…
Coherent Line Removal: Filtering out harmonically related line interference from experimental data, with application to gravitational wave detectors
Alicia M. Sintes, Bernard F. Schutz
We describe a new technique for removing troublesome interference from external coherent signals present in the gravitational wave spectrum. The method works when the interference…
Einstein's Equations with Asymptotically Stable Constraint Propagation
Othmar Brodbeck, Simonetta Frittelli, Peter Huebner +1
We introduce a proposal to modify Einstein's equations by embedding them in a larger symmetric hyperbolic system. The additional dynamical variables of the modified system are esse…
D=11 SUGRA as the Low Energy Effective Action of Matrix Theory: Three Form Scattering
Jan Plefka, Marco Serone, Andrew Waldron
We employ the LSZ reduction formula for Matrix Theory introduced in our earlier work to compute the t-pole S-matrix for three form-three form scattering. The result agrees complete…
All nonspherical perturbations of the Choptuik spacetime decay
Jose M. Martin-Garcia, Carsten Gundlach
We study the nonspherical linear perturbations of the discretely self-similar and spherically symmetric solution for a self-gravitating scalar field discovered by Choptuik in the c…
Supermembranes and M(atrix) Theory
Hermann Nicolai, Robert Helling
In these lectures, we review the D=11 supermembrane and supersymmetric matrix models at an introductory level. We also discuss some more recent developments in connection with non-…

Piotr Jaranowski, Andrzej Królak
We examine the accuracy of estimation of parameters of the gravitational-wave signals from spinning neutron stars that can be achieved from observations by Earth-based laser interf…

Matthias Staudacher
We introduce a systematic approach for treating the large N limit of matrix field theories.
Hamiltonian evolution and quantization for extremal black holes
Claus Kiefer, Jorma Louko
We present and contrast two distinct ways of including extremal black holes in a Lorentzian Hamiltonian quantization of spherically symmetric Einstein-Maxwell theory. First, we for…
