20 Feb 2019 | | Abstract: | AGN-driven outflows are considered as one of the processes driving the
co-evolution of supermassive black holes with their host galaxies. We present
integral field spectroscopy of six Type 2 AGNs at z < 0.1, which are selected
as AGNs without strong outflows based on the kinematics of [Oiii] gas. Using
spatially resolved data, we investigate the ionized gas kinematics and
photoionization properties in comparison with AGNs with strong outflows. We
find significant differences between the kinematics of ionized gas and stars
for two AGNs, which indicates the presence of AGN-driven outflows.
Nevertheless, the low velocity and velocity dispersion of ionized gas indicate
relatively weak outflows in these AGNs. Our results highlight the importance of
spatially-resolved observation in investigating gas kinematics and identifying
the signatures of AGN-driven outflows. While it is unclear what determines the
occurrence of outflows, we discuss the conditions and detectability of
AGN-driven outflows based on a larger sample of AGNs with and without outflows,
suggesting the importance of gas content in the host galaxies. | | Source: | arXiv, 1902.7560 | | Services: | Forum | Review | PDF | Favorites | |
