SUMMARY:The star formation history of nearby active galactic nuclei 
DESCRIPTION:The star formation history of nearby active galactic nuclei \nD
 r. Rogério Riffel\n\n \nSince the pioneering studies linking the mas
 s of  supermassive black holes (SMBH) with the velocity dispersion of thei
 r host galaxies bulges it has become accepted that the products of active 
 galactic nuclei (AGN) accretion and star-formation (SF) are somehow relate
 d. It is also accepted that nuclear SF and AGN can coexist in the inner re
 gion of galaxies, suggesting that the growth of SMBH (by gas accretion) an
 d galaxies (by forming stars) are coupled.  In terms of  galaxy evolu
 tion, it is established that AGN feedback plays a fundamental role by impa
 cting SF (quenching,  suppressing, or triggering). Cosmological simulation
 s performed without  the inclusion of feedback (SNR/AGN) effects are not a
 ble to reproduce  the low and high luminosity ends of the galaxy luminosit
 y function and  underestimate the ages of the stars of the most massive ga
 laxies when  compared with observations.  While observations have sho
 wn that nuclear  star formation is common in AGNs, properly measuring the 
 stellar population properties in  AGNs hosts is particularly difficult, si
 nce the active nucleus will  dilute the absorption features and contribute
  to a large number of  ionizing photons that will make it difficult to use
  emission line fluxes  to infer the stellar properties.  In this
  seminar, I will discuss the  results we have obtained in our group when m
 apping the stellar  population in the inner region of active galaxies, wit
 h a special focus  on the near-infrared spectral region, which allows for 
 a better  untangling of the AGN and stellar contributions for the spectral
  energy  distribution of the galaxies. \nZoom: https://rediris.z
