Multipolar Neutrino Radiation in Binary Neutron Star Mergers: Angular Structure, Rotational Variability, and Implications for Electron Fraction
Kutay Arınç Çokluk, Albino Perego, Federico Maria Guercilena +1
The angular structure and temporal variability of neutrino emission from binary neutron star mergers are characterized using fully general-relativistic simulations with energy-inte…
Evaluation of complex-valued error-like functions by the exponentially-convergent trapezoidal rule
Federico Maria Guercilena
The exponentially convergent trapezoidal rule is applied to a suitable integral representation of the Faddeeva function to derive a simple formula for its evaluation. I describe it…
Impact of Neutrino Flavor Conversions on Neutron Star Merger Dynamics, Ejecta, Nucleosynthesis, and Multi-Messenger Signals
Yi Qiu, David Radice, Sherwood Richers +3
We present numerical relativity simulations of binary neutron star mergers incorporating neutrino flavor transformations triggered by fast flavor instability, quantum many-body eff…
Open-source library for performance-portable neutrino reaction rates: Application to neutron star mergers
Leonardo Chiesa, Maitraya Bhattacharyya, Filippo Mazzini +3
A realistic and detailed description of neutrinos in binary neutron star (BNS) mergers is essential to build reliable models of such systems. To this end, we present BNS_NURATES, a…
Geometric and thermodynamic characterization of binary neutron star accretion discs
Alessandro Camilletti, Albino Perego, Federico Maria Guercilena +2
Accretion disks formed in binary neutron star mergers play a central role in many astrophysical processes of interest, including the launching of relativistic jets or the ejection…
Did a Kilonova Set Off in Our Galactic Backyard 3.5 Myr ago?
Leonardo Chiesa, Albino Perego, Federico Maria Guercilena
The recent detection of the live isotopes and in deep ocean sediments dating back to the past 3-4 Myr poses a serious challenge to the identificati…
Effects of nuclear matter properties in neutron star mergers
Maximilian Jacobi, Federico Maria Guercilena, Sabrina Huth +3
The dynamics in mergers of binary neutron star (BNS) systems depend sensitively on the equation of state (EOS) of dense matter. This has profound implications on the emission of gr…
Numerical relativity simulations of the neutron star merger GW190425: microphysics and mass ratio effects
A. Camilletti, L. Chiesa, G. Ricigliano +7
GW190425 was the second gravitational wave (GW) signal compatible with a binary neutron star (BNS) merger detected by the Advanced LIGO and Advanced Virgo detectors. Since no elect…
A new first-order formulation of the Einstein equations exploiting analogies with electrodynamics
H. Olivares, I. M. Peshkov, E. R. Most +2
The Einstein and Maxwell equations are both systems of hyperbolic equations which need to satisfy a set of elliptic constraints throughout evolution. However, while electrodynamics…
Neutrino emission from binary neutron star mergers: characterizing light curves and mean energies
Marco Cusinato, Federico Maria Guercilena, Albino Perego +4
Neutrinos are copiously emitted by neutron star mergers, due to the high temperatures reached by dense matter during the merger and its aftermath. Neutrinos influence the merger dy…
Shedding light on the angular momentum evolution of binary neutron star merger remnants: a semi-analytic model
Matteo Lucca, Laura Sagunski, Federico Guercilena +1
The main features of the gravitational dynamics of binary neutron star systems are now well established. While the inspiral can be precisely described in the post-Newtonian approxi…
On r-process nucleosynthesis from matter ejected in binary neutron starmergers
Luke Bovard, Dirk Martin, Federico Guercilena +3
When binary systems of neutron stars merge, a very small fraction of their rest mass is ejected, either dynamically or secularly. This material is neutron-rich and its nucleosynthe…
Conformal and covariant Z4 formulation of the Einstein equations: strongly hyperbolic first-order reduction and solution with discontinuous Galerkin schemes
Michael Dumbser, Federico Guercilena, Sven Koeppel +2
We present a strongly hyperbolic first-order formulation of the Einstein equations based on the conformal and covariant Z4 system (CCZ4) with constraint-violation damping, which we…
Entropy-limited hydrodynamics: a novel approach to relativistic hydrodynamics
Federico Guercilena, David Radice, Luciano Rezzolla
We present entropy-limited hydrodynamics (ELH): a new approach for the computation of numerical fluxes arising in the discretization of hyperbolic equations in conservation form. E…
Strong-Field Scattering of Two Black Holes: Numerics Versus Analytics
Thibault Damour, Federico Guercilena, Ian Hinder +3
We probe the gravitational interaction of two black holes in the strong-field regime by computing the scattering angle of hyperbolic-like, close binary-black-hole encounters as…
