线位移与亚pc超大质量双星黑洞

Line shifts and sub-pc super-massive binary black holes

Sasa Simic, Luka C. Popovic

摘要:

在这里,我们讨论的可能性,超大质量的双黑洞(SMBBH)检测,使用从一个双系统发射的宽线的位移。我们进行了一些模拟的形状和移动的$H_β$线从SMBBH发射,考虑到发射从两个不同的区域位于周围的黑洞,和运动学的影响,应该存在于SMBBH。在该模型中,我们将谱线的参数与黑洞的质量联系起来,发现谱线的峰移不仅依赖于系统转动和黑洞质量比的运动学效应,而且还是两个黑洞(BH)的单个质量的函数。

英文摘要:

Here we discuss the possibility of super-massive binary black hole (SMBBH) detection, using the shifts of the broad lines emitted from a binary system. We perform a number of simulations of shapes and shifts of $H_β$ lines emitted from SMBBHs, taking into account the emission from two different regions located around both black holes, and kinematical effects which should be present in a SMBBH. In the model we connect the parameters of the lines with the mass of black holes and find that the peak shift depends, not only on kinematical effects of system rotation and black hole mass ratio, but it is also a function of the individual masses of the two black holes (BHs).
