Research Abstract

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.
