摘要 (Abstract): 

Black hole system wind is a very important topic in recent years. On one hand, it is due to the fact that more and more observations show that strong winds are present in both AGNs and black hole X-ray binaries. Therefore,  wind is an important ingredient of black hole accretion system. Theoretically, it is important to study how can wind be produced in black hole accretion system and what is the effect of wind on black hole accretion flow/disk. On the other hand, observations show that in galaxies, the central black hole is tightly correlated with the evolution its host galaxy. Black hole wind can strongly interact with its host galaxy, at least in the region very close to the central engine.  A black hole accretion system mainly has two main modes, namely hot and cold modes. The wind from hot accretion flow have been studied intensively in recent years. However, the wind production by cold thin disk is still not clear. In this talk, I will first briefly review the wind production by hot accretion flow. Then, I will talk about wind production by cold thin disk. Finally, I will talk about wind feedback at parsec scale, where the fueling gas of black hole comes from.

主讲人简介 (Speaker's CV): 

部德福， 2010年于中国科学院上海天文台获得博士学位。2010年留上海天文台工作，现为研究员。工作领域为致密天体吸积相关的高能天体物理与活动星系核反馈。致密天体吸积方面，系统地研究了黑洞热吸积流中外流的驱动机制、外流的性质等，这些工作为活动星系核反馈研究提供了至关重要的物理参数。除了黑洞吸积外，近两年系统的研究了黑洞吸积和中子星吸积的异同。最近，研究了黑洞吸积系统的外流以及辐射对于parsec尺度上气体的反馈。
