Title Modeling of binary neutron star mergers: from simulations to multimessenger observations
Abstract With the advent of ground-based gravitational waves detectors, such as Advanced Ligo and Advanced Virgo, the era of multimessenger astrophysics from compact binary merger has started. Such a kind of events represent bright sources of gravitational waves and electromagnetic radiation, as well as neutrinos and heavy nuclei. The detection and interpretation of multimessenger signals from the collision of two compact objects requires a fruitful interplay between the observational efforts and the theoretical modeling. The pivotal role of all fundamental interactions, as well as the multiscale, multiphysics nature of the process, represents a great challenge in the path towards a deeper understanding of the coalescence process and of its rich phenomenology. In this talk, I will review our present understanding of the major processes involved in the merger of two neutron stars and on their impact on some of the many observable we can presently detect. A special emphasis will be given to the role of neutrinos and weak interactions.
