Abstract:
Feedback from active galactic nuclei (AGN) in general seems to play an
important role in the evolution of galaxies, although the impact of
AGN winds on their host galaxies is still pending on detailed
analysis.
We analyse the kinematics of a sample of 170 AGN host galaxies as
compared to those of a matched control sample of nonactive galaxies
from the MaNGA survey in order to characterise and estimate the
extents of the Narrow Line Region (NLR) and of the kinematically
disturbed region (KDR) by the AGN.
We define the observed NLR radius (rNLR,o) as the farthest distance
from the nucleus within which both [OIII]/Hβ and [NII]/Hα
ratios fall in the AGN region of the BPT diagram and the H equivalent
width is required to be larger than 3.0Å. The extent of the KDR
(rKDR,o) is defined as the distance from the nucleus within which the
AGN hosts galaxies shows a more disturbed gas kinematics than the
control galaxies.
The AGN [OIII]5007 luminosity ranges from 1039 to 1041erg/s, and
the kinematics derived from the [OIII] line profiles reveal that, on
average, the most luminous AGN (L[OIII]>3.8x1040erg/s) possess
higher residual difference between the gaseous and stellar velocities
and velocities dispersion than their control galaxies in all the
radial bins. Spatially resolved NLR's and KDR's were found in 55
and 46 AGN host galaxies, with corrected radii 0.2<rKDR,c<2.3kpc and
0.4<rNLR,c<10.1kpc, with a relation between the two given by
logrKDR,c=(0.53±0.12)logrNLR,c+(1.07±0.22), respectively. On
average, the extension of the KDR corresponds to about 30 per cent of
that of the NLR. Assuming that the KDR is due to an AGN outflow, we
have estimated ionised gas mass outflow rates that range between
10-5 and ∼1M☉/yr, and kinetic powers that range from 1034 to
1040erg/s.
Comparing the power of the AGN ionised outflows with the AGN
luminosities, they are always below the 0.05 LAGN model threshold for
having a an important feedback effect on their respective host
galaxies. The mass outflow rates (and power) of our AGN sample
correlate with their luminosities, populating the lowest AGN
luminosity range of the correlations previously found for more
powerful sources.
Description:
We have compared the ionised gas kinematics of a sample of 170 active
galaxies to those of a control sample of non-active galaxies from the
MaNGA survey.
