Coevolution of Black Holes and Galaxies in proto-active galactic nuclei and polarized X-ray emission

活动星系核（agn）通过将周围的气体吸积到质量约为10亿个太阳质量的中心黑洞（BHs）上，从而释放出大量的辐射，其亮度是典型星系的100倍。然而，超大质量黑洞的形成过程以及超大质量黑洞与星系之间共同演化的起源仍不清楚。因此，我们注意到年轻的agn“poro- agn”和超亮x射线源可能包含中等质量的黑洞。原agn辐射出强烈的远紫外辐射，因此不仅在黑洞的生长历史上，而且在星系的演化历史上都吸引了各种研究者。在这个项目中，我们试图揭示bh星系共同演化的机制。基于超亮x射线源的多历元x射线光谱数据，研究了中等质量黑洞是否真的存在。超大质量黑洞由周围的气体提供能量，并增加其质量。通过将我们的黑洞和吸积盘周围环面模型与观测到的近红外环面辐射进行比较，我们研究了agn中尘埃团块环面的结构。

Active galactic nuclei (AGNs) are radiating an enormous amount of emission as a hundred times more luminous than a typical galaxy, by accreting the surrounding gas onto the central black holes (BHs) with their masses of about a billion solar masses. However, the formation process(es) of the super-massive BHs and the origin(s) of the coevolution between super-massive BHs and galaxies are still unclear. Therefore, we notice young AGNs "poro-AGNs"and ultra-luminous X-ray sources which potentially harbor intermediate-mass BHs. Proto-AGNs radiate intense far-UV emission, and thereby attract various researchers in terms of not only the BH growth history but also the evolution history of galaxies. In this project, we try to unveil the mechanism of the BH-galaxy coevolution. Based on the multi-epoch X-ray spectral data of ultra-luminous X-ray sources, we investigate whether intermediate-mass BHs are really exist or not. Super-massive BHs are fed by the surrounding gas and increase their mass. By comparing our model of the torus surrounding the BH and the accretion disk with the observed near infra-red emission from such tori, we examined the structure of the dusty clumpy tori in AGNs.
