Mapping the feedback in the host galaxies of [O III] outflowing active nuclei

(Abstract)
We propose an Adaptive Optics (AO) assisted, optical  integral-field-unit 
(IFU) study for two nearest active galactic nuclei with prominent blueshifts 
in [O III] emission. We will map the mass outflow rate and  the kinetic power 
with  Kyoto3DII+AO188, which is {the first and only} AO-assisted, optical IFU 
on 8-10m telescopes in the world. We aim at answering to the basic (but still 
remained) questions {"is there really quasar-mode feedback?"} and  {"is it 
powerful enough to quench star formation} in host galaxies?". This project was 
approved before (S14A035N & S15A052A), and the data taken in bad conditions 
indicate that our feasibility estimation is appropriate.
(A) Optical band enables us to measure the gas density, whereas earlier AO-IFU 
studies performed at Near-IR inevitably suffer from the uncertainty of the 
density. (B) Our [OIII] blueshifting targets ensure that the outflow certainly 
reaches the narrow-line region (~galactic scale), in contrast with other 
outflow phenomena near black holes (observed in CIV, X-ray or broad absorption 
lines) (C) Since the [O III] blueshift happens only in the early stage of 
black hole growth, our targets are good sites for investigating the black hole-
galaxy coevolution.
