- W3037170147 abstract "ABSTRACT The role of feedback from active galactic nuclei (AGNs) in the evolution of galaxies is still not fully understood, mostly due to the lack of observational constraints in the multiphase gas kinematics on the 10–100 pc scales. We have used the Gemini Near-Infrared Integral Field Spectrograph (NIFS) to map the molecular and ionized gas kinematics in the inner 900 × 900 pc2 of the Seyfert galaxy NGC 1275 at a spatial resolution of ∼70 pc. From the fitting of the CO absorption bandheads in the K band, we derive a stellar velocity dispersion of 265 ± 26 km s−1, which implies a black hole mass of $M_{rm SMBH}=1.1^{+0.9}_{-0.5}times 10^9$ M⊙. We find hot (T ≳ 1000 K) molecular and ionized outflows with velocities of up to 2000 km s−1 and mass outflow rates of $2.7times 10^{-2}$ and $1.6, {rm M_odot }$ yr−1, respectively, in each of these gas phases. The kinetic power of the ionized outflows corresponds to only 0.05 per cent of the luminosity of the AGN of NGC 1275, indicating that they are not powerful enough to provide significant AGN feedback, but may be effective in redistributing the gas in the central region of the galaxy. The AGN-driven outflows seem to be responsible for the shocks necessary to produce the observed H2 and [Fe ii] line emission." @default.
