Our research is focused on cosmic explosions: the catastrophic deaths of stars. Huge amounts of energy are released within hours in events so bright they are seen from the edge of the Universe. The resulting extreme physical conditions involve huge densities, pressures and temperatures, strong magnetic fields, nuclear and high energy particle reactions, and strong relativistic effects (special and general). These topics are at the forefront of research in high energy particle astrophysics and gravity theories, with implications from the source of life to cosmology.
