Resolving Black Holes

An astrophysics research group at CU Boulder, JILA, and MPE Garching studying the observational properties of gas falling onto black holes (accretion flows) and their use as probes of strong gravity.

Research Areas

Extreme variability of accreting supermassive black holes
Rotation of high velocity gas around a supermassive black hole
Strong magnetic fields near the event horizon of M87
Orbiting gas near the event horizon of the Galactic center black hole
Sgr A* flares from magnetic reconnection
Using polarization to extract the black hole photon ring
