Introduction to dynamical horizons in numerical relativity

- E. Schnetter, B. Krishnan, F. Beyer
- Physics
- 4 April 2006

This paper presents a quasilocal method of studying the physics of dynamical black holes in numerical simulations. This is done within the dynamical horizon framework, which extends the earlier work… Expand

Quasilinear Hyperbolic Fuchsian Systems and AVTD Behavior in T2-Symmetric Vacuum Spacetimes

- Ellery Ames, F. Beyer, J. Isenberg, P. LeFloch
- Mathematics, Physics
- 9 May 2012

We set up the singular initial value problem for quasilinear hyperbolic Fuchsian systems of first order and establish an existence and uniqueness theory for this problem with smooth data and smooth… Expand

Lachnotalea glycerini gen. nov., sp. nov., an anaerobe isolated from a nanofiltration unit treating anoxic groundwater.

- Monika Jarzembowska, D. Sousa, F. Beyer, A. Zwijnenburg, C. Plugge, A. Stams
- Biology, Medicine
- International journal of systematic and…
- 1 February 2016

A strictly anaerobic bacterium, strain DLD10T, was isolated from a biofilm that developed on a nanofiltration membrane treating anoxic groundwater using glycerol as substrate. Cells were straight to… Expand

Numerical solutions of Einstein's equations for cosmological spacetimes with spatial topology S 3 and symmetry group U(1)

- F. Beyer, L. Escobar, J. Frauendiener
- Physics
- 21 May 2015

We apply a single patch pseudo-spectral scheme based on integer spin-weighted spherical harmonics presented in [1, 2] to Einstein’s equations. The particular hyperbolic reduction of Einstein’s… Expand

Numerical space-times near space-like and null infinity. The spin-2 system on Minkowski space

- F. Beyer, G. Doulis, J. Frauendiener, B. Whale
- Physics
- 24 July 2012

In this paper we demonstrate for the first time that it is possible to solve numerically the Cauchy problem for the linearisation of the general conformal field equations near spacelike infinity,… Expand

The Spin-2 Equation on Minkowski Background

- F. Beyer, G. Doulis, J. Frauendiener, B. Whale
- Physics
- 24 April 2013

The linearised general conformal field equations in their first and second order form are used to study the behaviour of the spin-2 zero-rest-mass equation on Minkowski background in the vicinity of… Expand

Investigations of solutions of Einstein's field equations close to λ-Taub–NUT

- F. Beyer
- Physics
- 26 April 2008

We present investigations of a class of solutions of Einstein's field equations close to the family of λ-Taub–NUT spacetimes. The studies are done using a numerical code introduced by the author… Expand

Non-genericity of the Nariai solutions: II. Investigations within the Gowdy class

- F. Beyer
- Physics
- 15 February 2009

This is the second of two papers in which we study the asymptotics of the generalized Nariai solutions and its relation to the cosmic no-hair conjecture. In the first paper, the author suggested… Expand

Second-order hyperbolic Fuchsian systems and applications

- F. Beyer, P. LeFloch
- Physics, Mathematics
- 1 November 2010

We introduce a new class of singular partial differential equations, referred to as the second-order hyperbolic Fuchsian systems, and we investigate the associated initial value problem when data are… Expand

Smooth Gowdy-symmetric generalized Taub–NUT solutions

We study a class of -Gowdy vacuum models with a regular past Cauchy horizon which we call smooth Gowdy-symmetric generalized Taub–NUT solutions. In particular, we prove the existence of such… Expand
