Structure of Stable Binary Neutron Star Merger Remnants: Role of Initial Spin
Wolfgang Kastaun, Riccardo Ciolfi, Andrea Endrizzi +1
We present general relativistic numerical simulations of binary neutron star (BNS) mergers with different initial spin configurations. We focus on models with stars of mass 1.4 M_s…
Short GRBs at the dawn of the gravitational wave era
G. Ghirlanda, O. S. Salafia, A. Pescalli +16
We derive the luminosity function and redshift distribution of short Gamma Ray Bursts (SGRBs) using (i) all the available observer-frame constraints (i.e. peak flux, fluence, peak…
Structure of Stable Binary Neutron Star Merger Remnants: a Case Study
Wolfgang Kastaun, Riccardo Ciolfi, Bruno Giacomazzo
In this work, we study the merger of two neutron stars with a gravitational mass of 1.4 M_sol each, employing the Shen-Horowitz-Teige equation of state. This equation of state is a…
Binary Neutron Star Mergers and Short Gamma-Ray Bursts: Effects of Magnetic Field Orientation, Equation of State, and Mass Ratio
Takumu Kawamura, Bruno Giacomazzo, Wolfgang Kastaun +4
We present fully GRMHD simulations of the merger of binary neutron star (BNS) systems. We consider BNSs producing a hypermassive neutron star (HMNS) that collapses to a spinning bl…
X-ray flashes powered by the spindown of long-lived neutron stars
Riccardo Ciolfi
X-ray flashes (XRFs) are a class of high-energy transients whose nature is still open to question. Similar in many aspects to common gamma-ray bursts (GRBs), their strong X-ray emi…
General Relativistic Magnetohydrodynamic Simulations of Binary Neutron Star Mergers with the APR4 Equation of State
Andrea Endrizzi, Riccardo Ciolfi, Bruno Giacomazzo +2
We present new results of fully general relativistic magnetohydrodynamic simulations of binary neutron star (BNS) mergers performed with the Whisky code. All the models use a piece…
