Constraining Dark Boson Decay Using Neutron Stars
Universe, 2023 Inspired by the well-known anomaly in the lifetime of the neutron, we investigated its consequences inside neutron stars. We first assessed the viability of the neutron decay hypothesis suggested by Fornal and Grinstein within neutron stars, in terms of ...

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

The mass distribution of Galactic double neutron stars
, 2019 The conventional wisdom, dating back to 2012, is that the mass distribution of Galactic double neutron stars is well-fit by a Gaussian distribution with a mean of $1.33 M_\odot$ and a width of $0.09 M_\odot$.

Axisymmetric general relativistic hydrodynamics: Long-term evolution of neutron stars and stellar collapse to neutron stars and black holes [PDF]
, 2003 We report a new implementation for axisymmetric simulation in full general relativity. In this implementation, the Einstein equations are solved using the Nakamura-Shibata formulation with the so-called cartoon method to impose an axisymmetric boundary ...
