Feeding versus feedback in AGN from near-infrared Integral Field
  Spectroscopy X: NGC5929
  We present near-infrared emission-line flux distributions, excitation and
kinematics, as well as stellar kinematics, of the inner 520x520 pc2$ of the
Seyfert 2 galaxy NGC5929. The observations were performed with the Gemini's
Near-Infrared Integral Field Spectrograph (NIFS) at a spatial resolution of 20
pc and spectral resolution of 40km/s in the J- and K-bands. The flux
distributions of H2, [FeII], [PII] and recombination lines are extended over
most of the field of view, with the highest intensity levels observed along
PA=60/240deg, and well correlated with the radio emission. The H2 and [FeII]
line emission are originated in thermal processes, mainly due to heating of the
gas by X-rays from the central Active Galactic Nucleus (AGN). Contribution of
shocks due to the radio jet is observed at locations co-spatial with the radio
hotspots at 0.5" northeast and 0.6" southwest of the nucleus, as evidenced by
the emission-line ratio and gas kinematics. The stellar kinematics shows
rotation with an amplitude at 250pc from the nucleus of 200 km/s after
corrected for the inferred inclination of 18.3deg. The stellar velocity
dispersion obtained from the integrated K-band spectrum is sigma*=133+/-8 km/s,
which implying on a mass for the supermassive black hole of M=5.2E7 Msun, using
the M-sigma* relation. The gas kinematics present three components: (1) gas in
the plane of the galaxy in counter-rotation relative to the stars; (2) an
outflow perpendicular to the radio jet that seems to be due to an equatorial
AGN outflow; (3) turbulence of the gas observed in association with the radio
hot spots, supporting an interaction of the radio jet with the gas of the disk.
We estimated the mass of ionized and warm molecular gas of ~1.3E6 Msun and ~470
Msun, respectively.
