Neutron stars are the densest astrophysical bodies in our universe which contain matter at extremely high density. I will discuss recent theoretical developments in revealing properties of neutron star matter from multi-messenger observations, and what we anticipate to discover in the near future with its implications for nuclear and particle physics.

Sophia Han earned her Ph.D. in physics from Washington University in St. Louis in 2015. During 2015-2018, she was a postdoc at the University of Tennessee Knoxville and a guest visitor at Oak Ridge National Laboratory. Since 2018 she has been a fellow of the N3AS (Network for Neutrinos, Nuclear Astrophysics, and Symmetries) Collaboration led by UC Berkeley, working on properties of dense matter on the QCD phase diagram and neutron star physics.
