Modelling the delayed shock-breakout emission following jet-launching binary neutron star mergers via relativistic magnetohydrodynamic simulations simulations

Matteo Pais, Riccardo Ciolfi, Andrea Pavan

In binary neutron star (BNS) mergers launching a relativistic jet, an electromagnetic (EM) signal is produced when the jet-driven shock breaks out of the merger ejecta. The observe…

Jet-environment interaction after delayed collapse in binary neutron star mergers

Jay V. Kalinani, Riccardo Ciolfi, Manuela Campanelli +4

We present general relativistic magnetohydrodynamic simulations of binary neutron star (BNS) mergers, where the collapse of the metastable massive neutron star (MNS) remnant leads…

Simulating the quasi-ballistic regime of a short Gamma-Ray Burst jet

Emma Dreas, Andrea Pavan, Riccardo Ciolfi +1

This study extends the 3D magnetohydrodynamic (MHD) simulation of a jet emerging from a binary neutron star (BNS) merger presented in Pavan et al. (2023), in which an incipient jet…

Evolution and afterglow emission of gamma-ray burst jets from binary neutron star mergers

Emma Dreas, Om Sharan Salafia, Andrea Pavan +2

Relativistic jets launched in binary neutron star (BNS) mergers are widely accepted as the engines powering most of the population of short gamma-ray bursts (GRBs). Understanding t…

Role of injection parameters in jet propagation through realistic binary neutron star merger environments

Andrea Pavan, Riccardo Ciolfi, Emma Dreas +1

After the first multi-messenger observation of a binary neutron star (BNS) merger powering a short-duration gamma-ray burst (GRB), GW170817-GRB 170817A, remarkable effort is ongoin…

Approaching ballistic motion in 3D simulations of gamma-ray burst jets in realistic binary neutron star merger environments

Emma Dreas, Andrea Pavan, Riccardo Ciolfi +1

Context. The concomitant observation of gravitational wave and electromagnetic signals from a binary neutron star (BNS) merger in 2017 confirmed that these events can produce relat…
