NGC 7469 as seen by MEGARA: new results from high-resolution IFU spectroscopy

In this talk I will present highlights from our recent work  about the analysis of high-resolution (R ~ 20 000) GTC/MEGARA integral-field unit spectroscopic observations, obtained during the commissioning run, in the inner region (12.5arcsec×11.3arcsec) of the active galaxy NGC7469, at spatial scales of 0.62 arcsec. We explore the kinematics, dynamics, ionisation mechanisms and oxygen abundances of the ionised gas, by modelling the Hα-[NII] emission lines at high signal-to-noise with multiple Gaussian components (Cazzoli et al. 2019).
