Long-lived neutron-star remnants from asymmetric binary neutron star mergers: element formation, kilonova signals and gravitational waves
Sebastiano Bernuzzi, Fabio Magistrelli, Maximilian Jacobi +3
We present 3D general-relativistic neutrino-radiation hydrodynamics simulations of two asymmetric binary neutron star mergers producing long-lived neutron stars remnants and spanni…
General relativistic hydrodynamic simulations of binary strange star mergers
Francesco Grippa, Aviral Prakash, Domenico Logoteta +2
We perform fully general-relativistic simulations of binary strange star mergers considering two different approaches for thermal effects. The first uses a cold equation of state (…
Revealing Phase Transition in Dense Matter with Gravitational Wave Spectroscopy of Binary Neutron Star Mergers
Pedro Luis Espino, Aviral Prakash, David Radice +1
We use numerical relativity simulations of binary neutron star mergers to show that high density deconfinement phase transitions (PTs) to quark matter can be probed using multimoda…
Muons in the aftermath of neutron star mergers and their impact on trapped neutrinos
Eleonora Loffredo, Albino Perego, Domenico Logoteta +1
In the upcoming years, present and next-generation gravitational wave observatories will detect a larger number of binary neutron star (BNS) mergers with increasing accuracy. In th…
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…
Probing the incompressibility of nuclear matter at ultra-high density through the prompt collapse of asymmetric neutron star binaries
A. Perego, D. Logoteta, D. Radice +5
Using 250 neutron star merger simulations with microphysics, we explore for the first time the role of nuclear incompressibility in the prompt collapse threshold for binaries with…
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…
Numerical relativity simulations of prompt collapse mergers: threshold mass and phenomenological constraints on neutron star properties after GW170817
Rahul Kashyap, Abhishek Das, David Radice +10
We determine the threshold mass for prompt (no bounce) black hole formation in equal-mass neutron star (NS) mergers using a new set of 227 numerical relativity simulations. We cons…
Signatures of deconfined quark phases in binary neutron star mergers
Aviral Prakash, David Radice, Domenico Logoteta +6
(abridged) We investigate the quark deconfinement phase transition in the context of binary neutron star (BNS) mergers. We employ a new finite-temperature composition-dependent equ…
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…

We report a new microscopic equation of state (EOS) of dense symmetric nuclear matter, pure neutron matter, and asymmetric and -stable nuclear matter at zero temperature using r…
Two coexisting families of compact stars: observational implications for millisecond pulsars
Sudip Bhattacharyya, Ignazio Bombaci, Domenico Logoteta +1
It is usually thought that a single equation of state (EoS) model "correctly" represents cores of all compact stars. Here we emphasize that two families of compact stars, viz., neu…

A phase of strong interacting matter with deconfined quarks is expected in the core of massive neutron stars. We investigate the quark deconfinement phase transition in cold (T = 0…
