Title: Connecting binary neutron star mergers and short gamma-ray burst jets in relativistic MHD simulations
Abstract:
The multimessenger observation of a binary neutron star (BNS) merger in 2017 confirmed that such systems can launch powerful jets and produce short gamma-ray bursts (SGRBs). Modelling the involved physical processes via numerical simulations is however extremely challenging. Despite great advancements in general relativistic MHD simulations of BNS mergers over the last decade, the jet formation mechanism and the nature of the central engine remain unclear. Moreover, the incipient jet propagation across the post-merger environment and up to the electromagnetic emission scales is typically modelled separately from the merger process, without a consistent end-to-end description. In this talk, I will review recent developments in simulations of BNS mergers, jet launching, and jet propagation up to a nearly ballistic expansion, and show how the different scales and evolution phases can be combined in a unified model.
