Neutron Stars

Neutron stars are the compact remnants of massive stars that have ended their lives in supernovae. We study many aspects of these exotic objects, both observationally and from a theoretical perspective. These include efforts to understand their emission mechanisms, measure their masses, model the population of neutron stars in our galaxy, and predict rates of neutron star binary mergers detectable by gravitational-wave observatories.
