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. |
