Inward and Outward Starburst Feedbacks and Growth of Supermassive Black Holes

다국어 초록 (Multilingual Abstract)

Based on the major merger scenario we propose a simple model to investigate the relation between
the starburst and the central active galactic nuclei (AGN). We argue that the momentum feedback
from the starburst rather than from the central black hole (BH) plays the most important role in the
main growth stage of both the BH and the bulge. We suggest that for small scale, the momentum
feedback from the starburst may exist in two directions. The outward starburst feedback can blow
some gas away to halt the star formation activity, and the growth of the BH is regulated by the
inward starburst feedback. The final BH mass is directly related to the maximum star formation
rate based on this scenario, and such a relation can be used to derive the MBH. and MBH.Mbulge
relations, which are consistent with recent observations and simulations. Our result suggests that
the BH undergoes its main growth in an obscured environment, which may be just the “pre-quasar”
phase, as some authors previously argued.
