Space-time diagrammatics

Piotr T. Chruściel, Christa R. Ölz, Sebastian J. Szybka

We introduce a new class of two-dimensional diagrams, the \emph{projection diagrams}, as a tool to visualize the global structure of space-times. We construct the diagrams for seve…

An efficient iterative method to reduce eccentricity in numerical-relativity simulations of compact binary inspiral

Michael Pürrer, Sascha Husa, Mark Hannam

We present a new iterative method to reduce eccentricity in black-hole-binary simulations. Given a good first estimate of low-eccentricity starting momenta, we evolve puncture init…

A lower bound for the mass of axisymmetric connected black hole data sets

Piotr T. Chruściel, Luc Nguyen

We present a generalisation of the Brill-type proof of positivity of mass for axisymmetric initial data to initial data sets with black hole boundaries. The argument leads to a str…

Oscillations toward the singularity of LRS Bianchi type IX cosmological models with Vlasov matter

Simone Calogero, J. Mark Heinzle

We analyze the dynamics of a class of cosmological solutions of the Einstein-Vlasov equations. These equations describe an ensemble of collisionless particles (which represent gala…

Length requirements for numerical-relativity waveforms

Mark Hannam, Sascha Husa, Frank Ohme +1

One way to produce complete inspiral-merger-ringdown gravitational waveforms from black-hole-binary systems is to connect post-Newtonian (PN) and numerical-relativity (NR) results…

Ghost points in inverse scattering constructions of stationary Einstein metrics

Piotr T. Chruściel, Luc Nguyen

We prove a removable singularities theorem for stationary Einstein equations, with useful implications for constructions of stationary solutions using soliton methods.
