Resolving Black Holes

An astrophysics research group at CU 91ÃÛÌÒ¸ó, JILA, and MPE Garching studying the observational properties of gas falling onto black holes (accretion flows) and their use as probes of strong gravity.

91ÃÛÌÒ¸ó 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
