Welcome to our homepage of the Structure and Evolution of Active Galactic Nucleus (AGNs) research group, lead by prof. Minfeng Gu, in Astrophysics Division of Shanghai Astronomical Observatory. Our group work on both observational and theoretical researches. For the observational science we focus on AGNs broad-band observations, especially on optical, X-ray and radio bands. For theoretical science we aimed at black hole accretion flow and it's radiation, large scale magnetic field evolution and jet formation/radiation mechnisms. Currently we have 6 staff members, 4 PhD students, and 1 graduate students.
