Microscopic equation of state of hot nuclear matter for numerical relativity simulations
Domenico Logoteta, Albino Perego, Ignazio Bombaci
A precise understanding of the equation of state (EOS) of dense and hot matter is key to modeling relativistic astrophysical environments, including core-collapse supernovae (CCSNe…
Mapping dynamical ejecta and disk masses from numerical relativity simulations of neutron star mergers
Vsevolod Nedora, Federico Schianchi, Sebastiano Bernuzzi +6
We present fitting formulae for the dynamical ejecta properties and remnant disk masses from the largest to date sample of numerical relativity simulations. The considered data inc…
Numerical Relativity Simulations of the Neutron Star Merger GW170817: Long-Term Remnant Evolutions, Winds, Remnant Disks, and Nucleosynthesis
Vsevolod Nedora, Sebastiano Bernuzzi, David Radice +7
We present a systematic numerical-relativity study of the dynamical ejecta, winds and nucleosynthesis in neutron star merger remnants. Binaries with the chirp mass compatible with…
Accretion-induced prompt black hole formation in asymmetric neutron star mergers, dynamical ejecta and kilonova signals
Sebastiano Bernuzzi, Matteo Breschi, Boris Daszuta +9
We present new numerical relativity results of neutron star mergers with chirp mass and mass ratios and using finite-temperature equations of state…
The Dynamics of Binary Neutron Star Mergers and of GW170817
David Radice, Sebastiano Bernuzzi, Albino Perego
With the first observation of a binary neutron star merger through gravitational waves and light GW170817, compact binary mergers have now taken the center stage in nuclear astroph…
Distinguishing the nature of ''ambiguous'' merging systems hosting a neutron star: GW190425 in low-latency
C. Barbieri, O. S. Salafia, M. Colpi +2
GW190425 is the newly discovered gravitational wave (GW) source consistent with a neutron star-neutron star merger with chirp mass of This value falls in the…
Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger S190814bv
K. Ackley, L. Amati, C. Barbieri +151
On 2019 August 14, the LIGO and Virgo interferometers detected a high-significance event labelled S190814bv. Preliminary analysis of the GW data suggests that the event was likely…
