" The Symbiotic Nature of AGN and SF activities of AGNs and their Host Galaxies : AKARI Perspective "

Ji Hoon Kim


The coevolution of supermassive black holes (SMBHs) and their host galaxies is one of the most important astrophysical processes due to the ubiquity of SMBHs. Although they are believed to coevolve through various physical processes, such as gas accretion and mergers, the details of these processes are still under hard scrutiny: what governs BH formation and growth, what regulates host galaxy growth, and if their growths have different phases with respect to each other. I will present results and progresses of various projects which I have been working to study the link between the growth of BHs via active galactic nucleus (AGN) activity and the growth of host galaxies through star formation (SF) activity. Most studies utilize a suite of NIR surveys and AKARI space telescope projects. A few highlights include; a discovery of z~6 low luminosity quasar, a census of SF activity of galaxies within North Ecliptic Pole surveys, and a strong correlation between AGN and SF activities of type-1 AGN host galaxies.

Seminars are also held at JAC, CFHT, and IfA.
