Description

Galactic circumnuclear regions, where stars and supermassive black holes interact with the interstellar medium, are crucial for understanding black hole feeding, feedback, and galaxy co-evolution. However, the connection between black hole feedback and the surrounding interstellar medium remains elusive. Using CAHA/PPAK and JWST observations, we investigate multi-scale outflows in the nearest low-luminosity active galactic nucleus (LLAGN), M81. Together with previously Chandra and Gemini/GMOS observations, we identify outflow signatures from sub-parsec to ~100-pc scales, providing a coherent view of the ionized gas kinematics and revealing a continuous feedback process. Our analysis offers new insights into how weak AGN regulate their immediate environments.
