Nuclear environments in nearby Seyfert galaxies / Dr Ming-Yi Lin (Institute of Astronomy & Astrophysics, Academia Sinica)

Abstract: An obscuring torus or disk made of dust and molecular gas is the key component in the unified model for active galactic nuclei (AGN). The dusty molecular gas flows from the galactic scale of ~100 parsec to the subparsec environment through a disk with moderate scale height. Such a cold disk may therefore be considered the AGN-feeding region. When the energy delivered by the AGN is sufficiently large to unbind the cold gas from black hole's gravitational potential, providing the conditions to launch the winds and outflows. In this talk, I will present the recent studies in the nuclear regions in the nearby Seyfert galaxies. The results allow us to discuss the nuclear star formation and the outflows within a physical scale of 10-200 pc around a supermassive black hole. In addition, I will introduce an efficient astronomical visualization tool specially for analyzing the radio data, named CARTA (Cube Analysis and Rendering Tool for Astronomy), and share the experience working as a software engineer.
