Formation and Observational Properties of Black Hole Winds

我们已经研究了黑洞风的形成和观测特性，黑洞风是从黑洞或黑洞吸积盘喷出的相对论性流出物。我们发现并区分了一个视光球，这是光子的最后一个散射面，还有一个热化面，光子在这里产生并散射到视光球。我们进一步获得了黑洞风在灰色和非灰色情况下的预期光谱。关于黑洞风，我们还研究了围绕发光黑洞吸积盘运动的气体层漂浮中的相对论性辐射传递问题。首先给出了平面平行流相对论辐射传递问题的形式化解。最后，我们还研究了辐射驱动的风和喷流。特别是，我们对半透明层的神奇速度有了新的认识。

We have examined the formation and observational properties of a black hole wind, which is a relativistic outflow ejected from a black hole or black-hole accretion disks. We found and distincted an apparent photosphere, which is the last scattering surface of photons, and a thermalization surface, where the photons are created and scattered off up to the apparent photosphere. We further obtained the expected spectra of a black hole wind for gran and non-gray cases.Relating to the black hole wind, we also examined the relativistic radiative transfer problem in gaseous strati floating of moving around a luminous black-hole accretion disks. We firstly found the formal solutions for the relativistic radiative transfer problem for the plane-parallel flow.Finally, we also studied the radiatively driven winds and jets. Especially, we obtained a new insight to the magic speed for a translucent stratus.
