Compact Objects

The Compact Objects group studies the astrophysics of neutron stars and black holes, using them as unique cosmic laboratories for exploring the physics of extreme gravitational and electromagnetic fields and of matter at extreme densities.

Recent gravitational-wave discoveries by LIGO, as well as recent progress in X-ray, gamma ray and radio observations, have opened an unprecedented observational window into black holes and neutron stars. A challenge for theorists is to match these observations with models, the physics of which cannot be readily tested in terrestrial conditions. The goal of the Compact Objects group is to produce a physical picture for a variety of extreme compact-object phenomena and to develop detailed mathematical models for these phenomena that can be tested by new observations.
