形成超大质量黑洞质量与星系球速度色散之间的关系

Shaping the relation between the mass of supermassive black holes and the velocity dispersion of galactic bulges

Man Ho Chan

摘要:

我利用超大质量黑洞吸积盘发出的辐射可以加热原星系中周围的气体,从而在星系形成过程中达到流体静力平衡。因此,黑洞质量M_BH和速度色散σ之间的相关性自然出现。即使用M_BH \leq 10^6 M_sun,结果也与观测数据的经验拟合基本一致。这个模型提供了一个清晰的图像,银河系超大质量黑洞的属性是如何与银河系隆起的动力学性质。

英文摘要:

I use the fact that the radiation emitted by the accretion disk of supermassive black hole can heat up the surrounding gas in the protogalaxy to achieve hydrostatic equilibrium during the galaxy formation. The correlation between the black hole mass M_BH and velocity dispersion σthus naturally arises. The result generally agrees with empirical fittings from observational data, even with M_BH \leq 10^6M_sun. This model provides a clear picture on how the properties of the galactic supermassive black holes are connected with the kinetic properties of the galactic bulges.
