摘要:Black hole is very common in the universe. The gas surrounding it falls onto it due to its strong gravitational force, this process is called black hole accretion. Black hole accretion is a fundamental physical process in astrophysics and plays an important role in active galactic nuclei,black hole X-ray binaries, Gamma-ray bursts, and tidal disruption events. Many important progresses have been made in recent years in this field, mainly attributed to the rapid development of numerical simulations. In this talk, I will first give a general introduction to black hole accretion; then I will focus on discussing the main development in this field in recent years, namely wind launched from accretion flow, including its observational evidence, launching mechanism, and role played in AGN feedback and galaxy evolution.
