Stellar populations in local AGNs: evidence for enhanced star formation
  in the inner 100pc
  In modern models and simulations of galactic evolution, the star formation in
massive galaxies is regulated by an ad hoc active galactic nuclei (AGN)
feedback process. However, the physics and the extension of such effects on the
star formation history of galaxies is matter of vivid debate. In order to shed
some light in the AGN effects over the star formation, we analyzed the inner
500$\times$500pc of a sample of 14 Seyfert galaxies using GMOS and MUSE
integral field spectroscopy. We fitted the continuum spectra in order to derive
stellar age, metallicity, velocity and velocity dispersion maps in each source.
After stacking our sample and averaging their properties, we found that the
contribution of young SP, as well as that of AGN featureless continuum both
peak at the nucleus. The fraction of intermediate-age SPs is smaller in the
nucleus if compared to outer regions, and the contribution of old SPs vary very
little within our field of view (FoV). We also found no variation of velocity
dispersion or metallicity within our FoV. Lastly, we detected an increase in
the dust reddening towards the center of the galaxies. These results lead us to
conclude that AGN phenomenon is usually related to a recent star formation
episode in the circumnuclear region.
