Multi-messenger Constraints on the Nuclear EOS: GW170817 and the future ahead |
|
Abstract |
The first directly-detected binary neutron star (NS) merger GW170817, as observed through both gravitaional-waves (GW) and across the electromagnetic (EM) spectrum, has opened a new page in multi-messenger astronomy. I will review and describe methods by which the (uncertain) equation-of-state (EOS) of cold dense nuclear matter can be constrained by combining inferences from both GW and EM signatures of binary NS mergers. Applying these methods to GW170817, I show that a new, strong, upper limit on the maximal mass of a non-rotating NS emerges. I will discuss these results, and overview the landscape ahead, addressing the question of - what are the parameter regions in which future multi-messenger observations of binary NS mergers will tighten constraints on the nuclear EOS? |
