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.
