Adaptive mesh and geodesically sliced Schwarzschild spacetime in 3+1 dimensions
, 1996 We present first results obtained with a 3+1 dimensional adaptive mesh code in numerical general relativity. The adaptive mesh is used in conjunction with a standard ADM code for the evolution of a dynamically sliced Schwarzschild spacetime (geodesic ...

Lattice Boltzmann model for numerical relativity [PDF]
Physical Review E, 2016 In the Bona-Masso formulation, Einstein equations are written as a set of flux conservative first order hyperbolic equations that resemble fluid dynamics equations. Based on this formulation, we construct a lattice Boltzmann model for Numerical Relativity.

Incorporating a Radiative Hydrodynamics Scheme in the Numerical-Relativity Code BAM
Universe, 2022 To study binary neutron star systems and to interpret observational data such as gravitational-wave and kilonova signals, one needs an accurate description of the processes that take place during the final stages of the coalescence, for example, through ...

Reducing reflections from mesh refinement interfaces in numerical relativity
, 2005 Full interpretation of data from gravitational wave observations will require accurate numerical simulations of source systems, particularly binary black hole mergers.

Higher dimensional Numerical Relativity: code comparison [PDF]
, 2014 The nonlinear behavior of higher dimensional black hole spacetimes is of interest in several contexts, ranging from an understanding of cosmic censorship to black hole production in high-energy collisions.

The 3+1 formalism in teleparallel and symmetric teleparallel gravity
European Physical Journal C: Particles and Fields, 2021 Teleparallel and symmetric teleparallel gravity offer platforms in which gravity can be formulated in interesting geometric approaches, respectively given by torsion and nonmetricity. In this vein, general relativity can be expressed in three dynamically

Invited papers from the international meeting on 'New Frontiers in Numerical Relativity' (Albert Einstein Institute, Potsdam, Germany, 17-21 July 2006) [PDF]
, 2007 Traditionally, frontiers represent a treacherous terrain to venture into, where hidden obstacles are present and uncharted territories lie ahead. At the same time, frontiers are also a place where new perspectives can be appreciated and have often been ...

Towards standard testbeds for numerical relativity [PDF]
Classical and Quantum Gravity, 2003 In recent years, many different numerical evolution schemes for Einstein's equations have been proposed to address stability and accuracy problems that have plagued the numerical relativity community for decades. Some of these approaches have been tested on different spacetimes, and conclusions have been drawn based on these tests. However, differences

A Brief Overview of Black Hole-Neutron Star Mergers
Frontiers in Astronomy and Space Sciences, 2020 Of the three main types of binaries detectable through ground-based gravitational wave observations, black hole-neutron star (BHNS) mergers remain the most elusive.
