Computational Cosmology: from the Early Universe to the Large Scale Structure
Living Reviews in Relativity, 2001 In order to account for the observable Universe, any comprehensive theory or model of cosmology must draw from many disciplines of physics, including gauge theories of strong and weak interactions, the hydrodynamics and microphysics of baryonic matter ...

What does a binary black hole merger look like? [PDF]
, 2015 We present a method of calculating the strong-field gravitational lensing caused by many analytic and numerical spacetimes. We use this procedure to calculate the distortion caused by isolated black holes and by numerically evolved black hole binaries ...

Gravitational-wave data analysis using binary black-hole waveforms
, 2008 Coalescing binary black-hole systems are among the most promising sources of gravitational waves for ground-based interferometers. While the \emph{inspiral} and \emph{ring-down} stages of the binary black-hole coalescence are well-modelled by analytical ...

Optimization of Finite-Differencing Kernels for Numerical Relativity Applications
Journal of Low Power Electronics and Applications, 2018 A simple optimization strategy for the computation of 3D finite-differencing kernels on many-cores architectures is proposed. The 3D finite-differencing computation is split direction-by-direction and exploits two level of parallelism: in-core ...
