We present our analysis of high-resolution ( R \sim 20 000 ) GTC/MEGARA integral-field unit spectroscopic observations , obtained during the commissioning run , in the inner region ( 12.5 arcsec \times 11.3 arcsec ) of the active galaxy NGC 7469 , at spatial scales of 0.62 arcsec .
We explore the kinematics , dynamics , ionisation mechanisms and oxygen abundances of the ionised gas , by modelling the H \alpha - [ N II ] emission lines at high signal-to-noise ( > 15 ) with multiple Gaussian components .
MEGARA observations reveal , for the first time for NGC 7469 , the presence of a very thin ( 20 pc ) ionised gas disc supported by rotation ( V/ \sigma = 4.3 ) , embedded in a thicker ( 222 pc ) , dynamically hotter ( V/ \sigma = 1.3 ) one .
These discs nearly co-rotate with similar peak-to-peak velocities ( 163 vs. 137 km s ^ { -1 } ) , but with different average velocity dispersion ( 38 \pm 1 vs. 108 \pm 4 km s ^ { -1 } ) .
The kinematics of both discs could be possibly perturbed by star-forming regions .
We interpret the morphology and the kinematics of a third ( broader ) component ( \sigma > 250 km s ^ { -1 } ) as suggestive of the presence of non-rotational turbulent motions possibly associated either to an outflow or to the lense .
For the narrow component , the [ N II ] /H \alpha ratios point to the star-formation as the dominant mechanism of ionisation , being consistent with ionisation from shocks in the case of the intermediate component .
All components have roughly solar metallicity .
In the nuclear region of NGC 7469 , at r \leq 1.85 arcsec , a very broad ( FWHM = 2590 km s ^ { -1 } ) H \alpha component is contributing ( 41 per cent ) to the global H \alpha - [ N II ] profile , being originated in the ( unresolved ) broad line region of the Seyfert 1.5 nucleus of NGC 7469 .
