Professional Interests The AGN team work on the study of active galactic nuclei (AGN). While all galaxies are now thought to harbor million-billion solar mass black holes at their center, only a small fraction of these are actively accreting gas; this accretion process results in the release of a large amount of energy very close to the nuclear black hole leading to these being known as ‘active’ galactic nuclei. X-rays are produced very close to the black hole and thus studying AGN in the X-ray bandpass allows us a unique probe of accreting systems and of material in the strong gravity regime.
