Astrophysical outflows driven by active galactic nuclei (AGNs) have been largely studied as a key phenomenon related to AGN feedback. Yet, characterizing and quantifying the impact on their host galaxies hasbeen challenging. To probe the kinematics of the gas in the inner regions of the galaxy, [OIII]λ5007 line has been used in a number of studies showing properties associated to AGN outflows. We present Gemini Multi-Object Spectrograph integral field unit data of the Narrow Line Seyfert 1 galaxy SDSSJ093643.13+505249.6 located at a distance of ∼ 200 Mpc. In this work, we investigate the kinematics and constrain the size of the outflow. Through a careful gaussian decomposition, we obtained different kinematic components for the emission lines in the blue end of the spectra, mainly Hβ and [OIII]. The ionized gas kinematics can be described as a superposition of a gravitational component that follows the stellar motion and an outflow-driven component that shows largeradial velocity (up to 500 km s −1 ) and large velocity dispersion (up to 700 km s −1 ). Using the spatially resolved measurements of the gas, we kinematically measure the size of the outflow, which is found to be ≥ 1.5 kpc. A bi-conic outflow together with a perpendicular gas disk model could explain the blue wing emission of [OIII] and the narrow component emission of Hβ. Finally, the spatially extended, large Hβ velocity dispersion suggest an impact of the AGN outflow on the Insterstellar Medium.
