According to the scenario in previous studies (e.g. Ricci et al. 2022), AGNs with large dust extinction and high Eddington ratio will cause the gas outflow and blow out surrounding materials, and will finally suppress both the AGN activity and the circumnuclear star formation. A detailed investigation of the outflow and the circumnuclear environment in these high-Eddington, dust-obscured AGNs is important to understand the effect of the AGN outflow on the galaxy evolution. We here perform circumnuclear-scale observations of seven nearby high-Eddington, dust-obscured AGNs, which we newly identified, with FOCAS-IFU. We observe the broad component of optical [OIII] lines, which is the indicator of the ionized-gas outflow, to estimate the physical properties and the spatial extent of the gas outflow (Jun et al. 2020). We also estimate the region with active star formation using a spatially-resolved BPT diagram (Baldwin et al. 1981) and compare it with the outflow extent to investigate the effects of the gas outflow on the circumnuclear star formation. This observation not only explores the nature of the gas outflow in nearby AGNs but also might provide hints on the nature of the gas outflow in high-z dust-obscured galaxies and the galaxy evolution at the ’cosmic noon’ by combining with JWST.
