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…

Machine Learning Detection of Non-Axisymmetric Fast Flavor Instabilities in Compact Objects
Madhurima Chakraborty, Sajad Abbar, Meng-Ru Wu +2
The paper applies machine‑learning classifiers to identify non‑axisymmetric electron lepton number (ELN) crossings, which signal fast neutrino flavor instabilities, using angular m…

Extending the infrastructure of the BAM code towards resistive general-relativistic magnetohydrodynamics: tests and first applications
Matthew Beaudoin, Maximilano Ujevic, Ramon Jaeger +4
The paper extends the BAM numerical‑relativity code to include resistive general‑relativistic magnetohydrodynamics, validates it with benchmark tests, and applies it to isolated an…
