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…
New constraints on radii and tidal deformabilities of neutron stars from GW170817
Elias R. Most, Lukas R. Weih, Luciano Rezzolla +1
We explore in a parameterized manner a very large range of physically plausible equations of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibi…
Using gravitational-wave observations and quasi-universal relations to constrain the maximum mass of neutron stars
Luciano Rezzolla, Elias R. Most, Lukas R. Weih
Combining the GW observations of merging systems of binary neutron stars and quasi-universal relations, we set constraints on the maximum mass that can be attained by nonrotating s…
On the stability and maximum mass of differentially rotating relativistic stars
Lukas R. Weih, Elias R. Most, Luciano Rezzolla
The stability properties of rotating relativistic stars against prompt gravitational collapse to a black hole are rather well understood for uniformly rotating models. This is not…
