Abstract
The Kerr black hole rotates with two parameters: mass M and angular momentum a and is characterized by the Kerr metric (Taylor and Wheeler 2000). Hence, a binary pair of a black hole and a star can create an accretion disc. A Kerr ray tracer algorithm was used to simulate accretion discs in the Seyfert-1 galaxy. The power law observed flux of relativistic emission lines, and Kerr Fourier image analysis methods were applied to the simulated discs. Simulated image characteristics were analyzed. Power laws were fitted to the simulated data of the Mrk110 accretion disc. Lastly, the simulated images were transformed into Fourier space and characteristics were discussed.
克尔黑洞的旋转有两个参数:质量M和角动量a，其特征是克尔度规(Taylor and Wheeler 2000)。因此，由黑洞和恒星组成的双星可以形成吸积盘。采用Kerr射线追踪算法模拟Seyfert-1星系中的吸积盘。利用幂律观测的相对论发射谱线通量，采用克尔傅立叶图像分析方法对模拟圆盘进行了分析。分析了模拟图像的特性。对Mrk110吸积盘的模拟数据进行幂律拟合。最后，将模拟图像转换到傅里叶空间，并对其特征进行了讨论。
