Abstract:
In this talk I will present results of fully general
relativistic simulations of binary neutron star (BNS) mergers and
discuss their connection with current and future astrophysical
observations. BNSs are one of the most promising sources of
gravitational waves (GWs) that we expect to detect in the next few
years with advanced LIGO and Virgo. But they may also emit powerful
electromagnetic signals and they are expected to be behind the engine
powering short gamma-ray bursts (SGRBs). During the first part of the
talk I will discuss the role of BNS merger simulations in predicting
the gravitational wave signal emitted during the merger and its
connection with the equation of state of NS matter. In the second part
I will instead discuss in detail the possible connection between the
central engine of SGRBs and the merger of magnetized neutron stars,
both in the case in which a black hole is promptly formed after merger
and in the case of the formation of a magnetar.
