Beyond moments: relativistic Lattice-Boltzmann methods for radiative transport in computational astrophysics
L. R. Weih, A. Gabbana, D. Simeoni +3
We present a new method for the numerical solution of the radiative-transfer equation (RTE) in multidimensional scenarios commonly encountered in computational astrophysics. The me…
A lower bound on the maximum mass if the secondary in GW190814 was once a rapidly spinning neutron star
Elias R. Most, L. Jens Papenfort, Lukas R. Weih +1
The recent detection of GW190814 featured the merger of a binary with a primary having a mass of and a secondary with a mass of . While th…
Two-moment scheme for general-relativistic radiation hydrodynamics: a systematic description and new applications
Lukas R. Weih, Hector Olivares, Luciano Rezzolla
We provide a systematic description of the steps necessary -- and of the potential pitfalls to be encountered -- when implementing a two-moment scheme within an Implicit-Explicit (…
The heavier the better: how to constrain mass ratios and spins of high-mass neutron-star mergers
Elias R. Most, Lukas R. Weih, Luciano Rezzolla
The first binary neutron-star merger event, GW170817, and its bright electromagnetic counterpart have provided a remarkable amount of information. By contrast, the second event, GW…
Postmerger Gravitational-Wave Signatures of Phase Transitions in Binary Mergers
Lukas R. Weih, Matthias Hanauske, Luciano Rezzolla
With the first detection of gravitational waves from a binary system of neutron stars, GW170817, a new window was opened to study the properties of matter at and above nuclear-satu…
Optimal neutron-star mass ranges to constrain the equation of state of nuclear matter with electromagnetic and gravitational-wave observations
Lukas R. Weih, Elias R. Most, Luciano Rezzolla
Exploiting a very large library of physically plausible equations of state (EOSs) containing more than members and yielding more than stellar models, we conduct a…
