Eccentricity as a signature of hierarchical subsolar-mass mergers in collapsar disks
Jiaxi Wu, Elias R. Most, Nils L. Vu +4
In this work, we investigate gravitational-wave signatures of a proposed subsolar-mass merger scenario resulting from fragmentation inside a collapsar accretion disk. This scenario…
A positivity-preserving adaptive-order finite-difference scheme for GRMHD
Nils Deppe, Lawrence E. Kidder, Saul A. Teukolsky +6
We present an adaptive-order positivity-preserving conservative finite-difference scheme that allows a high-order solution away from shocks and discontinuities while guaranteeing p…
Characterizing the Directionality of Gravitational Wave Emission from Matter Motions within Core-collapse Supernovae
Michael A. Pajkos, Steven J. VanCamp, Kuo-Chuan Pan +3
We analyze the directional dependence of the gravitational wave (GW) emission from 15 3D neutrino radiation hydrodynamic simulations of core-collapse supernovae. Using spin weighte…
Simulating neutron stars with a flexible enthalpy-based equation of state parametrization in SpECTRE
Isaac Legred, Yoonsoo Kim, Nils Deppe +4
Numerical simulations of neutron star mergers represent an essential step toward interpreting the full complexity of multimessenger observations and constraining the properties of…
SpECTRE: A Task-based Discontinuous Galerkin Code for Relativistic Astrophysics
Lawrence E. Kidder, Scott E. Field, Francois Foucart +11
We introduce a new relativistic astrophysics code, SpECTRE, that combines a discontinuous Galerkin method with a task-based parallelism model. SpECTRE's goal is to achieve more acc…
