Numerical Relativity Simulations of the Neutron Star Merger GW170817: Long-term Remnant Evolutions, Winds, Remnant Disks, and Nucleosynthesis [PDF]
, 2020 We present a systematic numerical relativity study of the dynamical ejecta, winds, and nucleosynthesis in neutron star (NS) merger remnants. Binaries with the chirp mass compatible with GW170817, different mass ratios, and five microphysical equations of

Aligned-spin neutron-star–black-hole waveform model based on the effective-one-body approach and numerical-relativity simulations [PDF]
Physical Review D, 2020 After the discovery of gravitational waves from binary black holes (BBHs) and binary neutron stars (BNSs) with the LIGO and Virgo detectors, neutron-star black holes (NSBHs) are the natural next class of binary systems to be observed.

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 ...

Numerical relativity simulation of GW150914 in Einstein-dilaton-Gauss-Bonnet gravity [PDF]
, 2020 A present challenge in testing general relativity (GR) with binary black hole gravitational wave detections is the inability to perform model-dependent tests due to the lack of merger waveforms in beyond-GR theories.

Assessing the readiness of numerical relativity for LISA and 3G detectors [PDF]
Physical Review D, 2020 Future detectors such as LISA promise signals at signal-to-noise ratios potentially in the thousands and data containing simultaneous signals. Is numerical relativity prepared for this new data analysis challenge?
