Description

A detailed description of the properties of dense matter in extreme conditions, as those within Neutron Star cores, is still an open problem, whose solution is hampered by both the lack of empirical data and by the difficulties in developing a suitable theoretical framework for the microscopic nuclear dynamics in such regimes. The detection of gravitational waves from the first observed coalescence of two neutron stars, GW170817, has opened the possibility to exploit gravitational waves as a new window to understand the behavior of nuclear matter.
We report here the results of a study aimed at inferring the properties of the repulsive three-nucleon interaction [1] driving the stiffness of the equation of state at high densities, by performing bayesian inference on current and future astrophysical observations.
We have also explored the potential of the Einstein Telescope which is expected to be able of largely improving our knowledge of nuclear dynamics in the upcoming future.
