Abstract:
The tight correlation between the mass of supermassive black hole (SMBH) and the properties of host spheroidal bulge component, suggests a SMBH co-evolves with its host galaxy. However, the relevant physics behind this co-evolutionary pathway is still unclear, the crucial questions include, how the raw material can go through the nuclear regions and further to trigger AGN activity and how the ejected gas from AGN can deposit energy to the host galaxy. Most of the literary works are limited to the telescope capability, focusing on the gas and stars properties on the galactic bulge scale, which corresponds to ~500 pc. In this talk, I will present recent high-resolution observations at near-infrared wavelengths (VLT adaptive optics mode) and at millimeter wavelengths (IRAM-PdBI and IRAM-NOEMA). It allows us to study the nuclear environments within the physical scale of 10-200 pc, and further I will discuss the star formation and the jet-ISM interactions of nearby Seyfert galaxies.
