Numerical Simulations of Dark Matter Admixed Neutron Star Binaries

Particles, 2022
Multi-messenger observations of compact binary mergers provide a new way to constrain the nature of dark matter that may accumulate in and around neutron stars.

Gravitational wave extraction and outer boundary conditions by perturbative matching [PDF]

, 1997
We present a method for extracting gravitational radiation from a three-dimensional numerical relativity simulation and, using the extracted data, to provide outer boundary conditions.

Numerical Relativity and Astrophysics [PDF]

Annual Review of Astronomy and Astrophysics, 2014
Throughout the Universe many powerful events are driven by strong gravitational effects that require general relativity to fully describe them. These include compact binary mergers, black hole accretion, and stellar collapse, where velocities can approach the speed of light and extreme gravitational fields (ΦNewt/c2≃1) mediate the interactions.

Status of NINJA: the Numerical INJection Analysis project [PDF]

, 2009
The 2008 NRDA conference introduced the Numerical INJection Analysis project (NINJA), a new collaborative effort between the numerical relativity community and the data analysis community.

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.
