The first 62 AGN observed with SDSS-IV MaNGA - II: resolved stellar
  populations
  We present spatially resolved stellar population age maps, average radial
profiles and gradients for the first 62 Active Galactic Nuclei (AGN) observed
with SDSS-IV MaNGA to study the effects of the active nuclei on the star
formation history of the host galaxies. These results, derived using the
STARLIGHT code, are compared with a control sample of non-active galaxies
matching the properties of the AGN hosts. We find that the fraction of young
stellar populations (SP) in high-luminosity AGN is higher in the inner ($R \leq
0.5\,R_e$) regions when compared with the control sample; low-luminosity AGN,
on the other hand, present very similar fractions of young stars to the control
sample hosts for the entire studied range ($1\,R_e$). The fraction of
intermediate age SP of the AGN hosts increases outwards, with a clear
enhancement when compared with the control sample. The inner region of the
galaxies (AGN and control galaxies) presents a dominant old SP, whose fraction
decreases outwards. We also compare our results (differences between AGN and
control galaxies) for the early and late-type hosts and find no significant
differences. In summary, our results suggest that the most luminous AGN seems
to have been triggered by a recent supply of gas that has also triggered recent
star formation ($t\,\leq\,40\,Myrs$) in the central region.
