Constraining neutron-star matter with microscopic and macroscopic collisions.

ABSTRACT: Interpreting high-energy, astrophysical phenomena, such as supernova explosions or neutron-star collisions, requires a robust understanding of matter at supranuclear densities. However, our knowledge about dense matter explored in the cores of neutron stars remains limited. Fortunately, dense matter is not probed only in astrophysical observations, but also in terrestrial heavy-ion collision experiments. Here we use Bayesian inference to combine data from astrophysical multi-messenger observations of neutron stars^1-9 and from heavy-ion collisions of gold nuclei at relativistic energies^10,11 with microscopic nuclear theory calculations^12-17 to improve our understanding of dense matter. We find that the inclusion of heavy-ion collision data indicates an incre
