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…

Dynamical ejecta synchrotron emission as possible contributor to the changing behaviour of GRB170817A

Vsevolod Nedora, David Radice, Sebastiano Bernuzzi +5

Over the past three years, the fading non-thermal emission from the GW170817 remained generally consistent with the afterglow powered by synchrotron radiation produced by the inter…

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…

Thermodynamics conditions of matter in the neutrino decoupling region during neutron star mergers

Andrea Endrizzi, Albino Perego, Francesco M. Fabbri +6

Neutrino-matter interactions play a key role in binary neutron star mergers. Thermodynamics conditions at the surfaces where neutrinos decouple from matter influence neutrino spect…

Spiral-wave wind for the blue kilonova

Vsevolod Nedora, Sebastiano Bernuzzi, David Radice +3

The AT2017gfo kilonova counterpart of the binary neutron star merger event GW170817 was characterized by an early-time bright peak in optical and UV bands. Such blue kilonova is co…
