The extreme astrophysics group uses a variety of ground- and space-based observatories to study astronomical phenomena that radiate X-rays or gamma-rays, or produce relativistic particles. Some areas of attention include: accretion onto compact objects (white dwarfs, neutron stars, black holes); measuring the masses and luminosity of black holes; gamma-ray bursts and their afterglows; gravitational wave signals from distant black hole mergers; jets from neutron stars and black holes; pulsar wind nebulae and supernova remnants; and tests of General Relativity.
