Modelling of binary neutron star mergers in the multimessenger Astrophysics era
video-meeting, June 17, 2020; 9:30 AM
ABSTRACT
With the advent of ground-based GW detectors and other observational facilities, coalescing compact binary mergers have become unique laboratories for fundamental physics at the extreme. The first multimessenger observation of a binary neutron star merger in 2017 provided a glance of the many opportunities that multimessenger astrophysics will possibly disclose in the years to come. All four fundamental interactions play a key role in setting the properties of the observables associated with these powerful stellar collisions. Thus, they need to be taken into account to provide reliable predictions and interpretations of multimessenger observations. In this talk, I will provide an overview of the most recent results obtained in Trento by the Teongrav initiative in modelling binary neutron star mergers from first principles. I will discuss, for example, its implications in exploring the equation of state of dense nuclear matter and in unveiling the origin of the heaviest elements in the Universe. I will also discuss the challenges in the field and our approach to them, as well as the interplay of our work with observational facilities.
