Abstract: Recent theoretical studies of the Active Galactic Nuclei (AGN) have suggested that the "torus" surrounded by the nucleus is not static and uniform, but rather dynamic and inhomogeneous. The so-called "torus" should be a part of the multi-phase structure of the circumnuclear gas in the central sub-pc to 100 pc. We here investigate multi-wavelength emissions from the multi-phase interstellar medium around AGNs, based on our "radiation-driven fountain model”. As an example, we here discuss the nearest type-2 AGN: Circinus galaxy. Our model consistently explains the observed spectral energy distribution. Using a snapshot of our 3-D radiation-hydrodynamic simulations as an input, we conducted post-processed radiative transfer simulations for molecular/atomic and ionized gas in the central 16 pc. We compare the results with past and future observations by ALMA, VLTI, and X-ray satellites. As usual we will offer fruits, snacks and soft drinks in the lounge area.
