Neutron stars are some of the most extreme forms of matter in the Universe.  As such, they provide a window into the behavior of matter in conditions not producible in a laboratory, and thereby allowing us a unique probe into fundamental physics.

When two neutron stars collide, they emit gravitational waves, which we can detect with observatories like LIGO and Virgo.  Imprinted in the waves is information regarding how massive the stars are, how fast they are spinning, and how malleable they are.  Using this information, we can place constraints on the properties of their matter, represented by the equation of state.  In this presentation, I detail a novel statistical framework for self-consistently combining information from multiple neutron star collisions, providing us with an increasingly precise equation of state as we detect more collisions.
