The GW Astrophysics Group
Members of the GW astrophysics group have done research in nuclear and particle physics for many years, going back to George Gamow, the developer of the hot Big Bang Theory of the Universe. With the rapid expansion of information in high-energy astrophysics due to new satellite data of unprecedented quality, and with the convergence of central themes in nuclear physics and astronomy in recent years, our group is now investigating new fundamental questions in astrophysics.
Our current interests center on understanding the underlying physical processes occurring near extremely compact and dense objects such as neutron stars and black holes. We study these processes through the analysis of x-ray and gamma-ray data that have been collected by a number of space-borne telescopes. Gamma-ray bursts (GRBs) are associated with some of the most energetic and explosive events in the Universe. We explore the mechanisms that lead to the observed spectra of GRBs and the released energy. Neutron stars born with very strong magnetic fields, called magnetars, are also of special interest. Other areas of study include the evolution of very massive stars and their interactions with the interstellar medium.
The GW group benefits extensively through collaborations with colleagues at NASA/Goddard Space Flight Center in Greenbelt, Maryland and around the world.
