We present two-dimensional maps of emission-line fluxes and kinematics, as well as of the stellar kinematics of the central few kpc of five bright nearby Seyfert galaxies -Mrk 6, Mrk 79, Mrk 348, Mrk 607 and Mrk 1058 -obtained from observations with the Gemini Multi-Object Spectrograph (GMOS) Integral Field Unit (IFU) on the Gemini North Telescope. The data cover the inner 3. ′′ 5×5. ′′ 0 -corresponding to physical scales in the range 0.6×0.9 to 1.5×2.2 kpc 2 -at a spatial resolution ranging from 110 to 280 pc with a spectral coverage of 4300 -7100 Å and velocity resolution of ≈ 90 km s −1 . The gas excitation is Seyfert like everywhere but show excitation, but show excitation gradients that are correlated with the gas kinematics, reddening and/or the gas density. The gas kinematics show in all cases two components: a rotation one similar to that observed in the stellar velocity field, and an outflow component. In the case of Mrk607, the gas is counter-rotating relative to the stars. Enhanced gas velocity dispersion is observed in association to the outflows according to two patterns: at the locations of the highest outflow velocities along the ionization axis or perpendicularly to it in a strip centered at the nucleus that we attribute to an equatorial outflow. Bipolar outflows are observed in Mrk 348 and Mrk 79, while in Mrk 1058 only the blueshifted part is clearly observed, while in the cases of Mrk 6 and Mrk 607 the geometry of the outflow needs further constraints from modeling to be presented in a forthcoming study, where the mass flow rate and powers will also be obtained.

We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini Multi-Object Spectrograph-integral field unit observations at spatial resolutions of ∼110–280 pc. We study the distributions of electron temperature in active galaxies and find temperatures varying in the range from ∼8000 to $\gtrsim 30\, 000\,$K. Shocks due to gas outflows play an important role in the observed temperature distributions of Mrk 79 and Mrk 348, while standard photoionization models reproduce the derived temperature values for Mrk 607. In Mrk 79 and Mrk 348, we find direct evidence for shock ionization with overall orientation orthogonal to the ionization axis, where shocks can be easily observed as the active galactic nuclei radiation field is shielded by the nuclear dusty torus. This also indicates that even when the ionization cones are narrow, the shocks can be much wider angle.

We use Gemini Multi-Object Spectrograph (GMOS) Integral Field Unit (IFU) observations of the inner 285×400 pc 2 region of the Seyfert 2 galaxy NGC 5643 to map the [S i i i]λ9069 emission-line flux distribution and kinematics, as well as the stellar kinematics, derived by fitting the Ca i iλλλ8498,8542,8662 triplet, at a spatial resolution of 45 pc. The stellar velocity field shows regular rotation, with a projected velocity of 100 km s −1 and kinematic major axis along Position Angle P A = −36 • . A ring of low stellar velocity dispersion values (∼70 km s −1 ), attributed to young/intermediate age stellar populations, is seen surrounding the nucleus with radius of 50 pc. We found that the [S i i i] flux distribution shows an elongated structure along the east-west direction and its kinematics is dominated by outflows within a bi-cone at an ionized gas outflow rate of 0.3 M yr −1 . In addition, velocity slices across the [S i i i]λ9069 emission-line reveal a kinematic component attributed to rotation of gas in the plane of the galaxy.

We use Gemini Multi-Object Spectrograph (GMOS) Integral Field Unit (IFU) observations of a sample of 5 bright nearby Seyfert galaxies to map their emission-line flux distributions and kinematics at a spatial resolution ranging from 110 to 280 pc. For all galaxies, the gas kinematics show two components: a rotation and an outflow component.
