X-ray spectral study of blackhole accretion disks

黑洞周围的吸积盘向太空发射X射线。我们利用了几个黑洞的朱雀宽波段数据，并评估了黑洞周围的引力能量是如何释放的。我们还计算了理论（光学厚）吸积盘模型，其中考虑磁盘的垂直结构，并测试与朱雀数据的高状态黑洞。然后我们发现，有一个关键的参数，这起着重要的作用，在磁盘的垂直结构失踪。

Accretion disks around blackholes emit X-ray into the space. We utilized the Suzaku wide band data of several black holes, and evaluated how gravitational energy was released around black holes. We also calculated theoretical (optically thick) accretion disk models, which take disk vertical structure into account, and tested them with the Suzaku data of a high state black hole. Then we found that there is a missing key parameter, which plays an important role in the disk vertical structure.
