Particle-acceleration mechanisms in multispecies relativistic plasmas
Claudio Meringolo, Mario Imbrogno, Alejandro Cruz-Osorio +2
While collisionless plasmas are ubiquitously present near astrophysical compact objects, the impact that their composition has on the high-energy emission is presently unknown. We…
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…
The Ep-Liso correlation: A new diagnostic tool for kilonova transients
Ruben Farinelli, Fabrizio Cogato, Mattia Bulla +10
The AT2017gfo kilonova transient remains a unique multi-messenger event thanks to its proximity (z=0.00987) and the possibility to investigate time-resolved spectra, providing evid…
Ring Asymmetry and Spin in M87*
Vadim Bernshteyn, Nicholas S. Conroy, Michi Bauböck +263
Event Horizon Telescope (EHT) images of the supermassive black hole M87* depict an asymmetric ring of emission. General relativistic magnetohydrodynamic (GRMHD) models of M87* and…
Listening to the long ringdown: A novel way to pinpoint the EOS in neutron-star cores
Christian Ecker, Tyler Gorda, Aleksi Kurkela +1
Gravitational waves (GWs) from binary neutron star (BNS) merger remnants complement constraints from the inspiral phase, mass-radius measurements, and microscopic theory by providi…
Dense Matter in Neutron Stars with eXTP
Ang Li, Anna L. Watts, Guobao Zhang +82
In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…
Physics-Informed Priors Improve Gravitational-Wave Constraints on Neutron-Star Matter
Spencer J. Magnall, Christian Ecker, Luciano Rezzolla +2
Gravitational-wave astronomy shows great promise in determining nuclear physics in a regime not accessible to terrestrial experiments. We introduce physics-informed priors constrai…
Postmerger: a new and dominant contribution to the gravitational-wave background from binary neutron stars
Léonard Lehoucq, Irina Dvorkin, Luciano Rezzolla
The stochastic gravitational-wave background (SGWB) generated by the inspiral and merger of binary neutron stars is traditionally modelled assuming that the inspiral is promptly fo…
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…
On the impact of neutrinos on the launching of relativistic jets from "magnetars" produced in neutron-star mergers
Carlo Musolino, Luciano Rezzolla, Elias R. Most
A significant interest has emerged recently in assessing whether collimated and ultra-relativistic outflows can be produced by a long-lived remnant from a binary neutron-star (BNS)…
Constraining the equation of state in neutron-star cores via the long-ringdown signal
Christian Ecker, Tyler Gorda, Aleksi Kurkela +1
Multimessenger signals from binary neutron star (BNS) mergers are promising tools to infer the largely unknown properties of nuclear matter at densities that are presently inaccess…
"Extended emission" from fallback accretion onto merger remnants
Carlo Musolino, Raphaël Duqué, Luciano Rezzolla
Using a set of general-relativistic magnetohydrodynamics simulations that include proper neutrino transfer, we assess for the first time the role played by the fallback accretion o…
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…
On the Deconfinement Phase Transition in Neutron-Star Mergers
Elias R. Most, L. Jens Papenfort, Veronica Dexheimer +3
We study in detail the nuclear aspects of a neutron-star merger in which deconfinement to quark matter takes place. For this purpose, we make use of the Chiral Mean Field (CMF) mod…
Beyond second-order convergence in simulations of magnetised binary neutron stars with realistic microphysics
Elias R. Most, L. Jens Papenfort, Luciano Rezzolla
We investigate the impact of using high-order numerical methods to study the merger of magnetised neutron stars with finite-temperature microphysics and neutrino cooling in full ge…
Impact of high spins on the ejection of mass in GW170817
Elias R. Most, L. Jens Papenfort, Antonios Tsokaros +1
Following the detection of GW170817 and the accompanying kilonova AT2017gfo, it has become crucial to model and understand the various channels through which mass is ejected in neu…
Magnetic field amplification by the r-mode instability
Andrey I. Chugunov, John L. Friedman, Lee Lindblom +1
We discuss magnetic field enhancement by unstable r-modes (driven by the gravitational radiation reaction force) in rotating stars. In the absence of a magnetic field, gravitationa…
