A scalable elliptic solver with task-based parallelism for the SpECTRE numerical relativity code

Nils L. Vu, Harald P. Pfeiffer, Gabriel S. Bonilla +10

Elliptic partial differential equations must be solved numerically for many problems in numerical relativity, such as initial data for every simulation of merging black holes and n…

The SpECTRE Cauchy-characteristic evolution system for rapid, precise waveform extraction

Jordan Moxon, Mark A. Scheel, Saul A. Teukolsky +5

We give full details regarding the new Cauchy-characteristic evolution (CCE) system in SpECTRE. The implementation is built to provide streamlined flexibility for either extracting…

High Precision Ringdown Modeling: Multimode Fits and BMS Frames

Lorena Magaña Zertuche, Keefe Mitman, Neev Khera +12

Quasi-normal mode (QNM) modeling is an invaluable tool for characterizing remnant black holes, studying strong gravity, and testing GR. Only recently have QNM studies begun to focu…

Simulating magnetized neutron stars with discontinuous Galerkin methods

Nils Deppe, François Hébert, Lawrence E. Kidder +33

Discontinuous Galerkin methods are popular because they can achieve high order where the solution is smooth, because they can capture shocks while needing only nearest-neighbor com…

A high-order shock capturing discontinuous Galerkin-finite-difference hybrid method for GRMHD

Nils Deppe, François Hébert, Lawrence E. Kidder +1

We present a discontinuous Galerkin-finite-difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohy…

Efficient simulations of high-spin black holes with a new gauge

Yitian Chen, Nils Deppe, Lawrence E. Kidder +1

We present a new choice of initial data for binary black hole simulations that significantly improves the efficiency of high-spin simulations. We use spherical Kerr-Schild coordina…
