AbstractTo reveal triggers of active galactic nucleus (AGN) and nuclear starburst generations and effects of the central activities to the circumnuclear environments, we propose the mid-infrared spectroscopic observations not only in central nuclei but also in the environments very close to central nuclei. The environments provide important information on supplying fuel to galactic nuclei, evidence for presence of materials processed by central activities and a connection between a nucleus and a host galaxy. To perform this kind of observations, we need a high contrast capability to reduce halo components of a point spread function of a bright central core. Reducing the halo components will be effective in not only obtaining the information of the faint environments around the core but also reducing the observing time. The SPICA Coronagraph Instrument (SCI) will provide such a high contrast capability in the mid-infrared. Using the SCI, we will obtain the circumnuclear structures and the compositions of dust, especially silicate and polycyclic aromatic carbons, in the environments very close to the bright central core in AGNs and nuclear starburst galaxies.
