Spinning down neutron-star merger remnants with the Tayler-Spruit dynamo: Global simulations reveal the formation of massive disks and neutron-rich ejecta
Harry Ho-Yin Ng, Elias R. Most
The paper presents global simulations of long-lived neutron-star merger remnants that include a subgrid model for the Tayler‑Spruit dynamo, showing rapid spin‑down, formation of a…
GRACE: An Open-Source Framework for GPU-Accelerated Numerical Relativity
Carlo Musolino, Christian Ecker, Konrad Topolski +6
We present GRACE, a new GPU-accelerated numerical-relativity framework designed to run efficiently on heterogeneous high-performance computing platforms. Developed from scratch and…
Distinct neutrino signatures and onset condition of quark deconfinement in accretion-induced collapse of white dwarfs
Juno C. L. Chan, Harry Ho-Yin Ng, Patrick Chi-Kit Cheong
We present the first general relativistic, neutrino-radiation hydrodynamics simulations of accretion-induced collapse (AIC) extending to seconds after core bounce, using realistic…
The initial spin matters: the impact of rapid rotation on magnetic-field amplification at merger
Harry Ho-Yin Ng, Jin-Liang Jiang, Luciano Rezzolla
A couple of milliseconds after the merger of a binary system of neutron stars can play a fundamental role in amplifying the comparatively low initial magnetic fields into magnetar…
Long-term impact of the magnetic-field strength on the evolution and electromagnetic emission by neutron-star merger remnants
Jin-Liang Jiang, Harry Ho-Yin Ng, Michail Chabanov +1
Numerical simulations are essential to understand the complex physics accompanying the merger of binary systems of neutron stars. However, these simulations become computationally…
Accurate muonic interactions in neutron star mergers and impact on heavy-element nucleosynthesis
Harry Ho-Yin Ng, Carlo Musolino, Samuel D. Tootle +1
The abundances resulting from -process nucleosynthesis as predicted by simulations of binary neutron star (BNS) mergers remain an open question as the current state of the art i…
