Young and Intermediate Stellar population in Seyfert 2 galaxies
  We present and discuss near-ultraviolet and optical ground-based spectra of the 20 brightest Seyfert 2 nuclei, and HST ultraviolet images and ultraviolet spectroscopy for a few of them. The goal is to study the starburst-AGN connection and the origin of the featureless continuum. The results indicate that half of the nuclei in the sample harbor a young and/or intermediate age population. These stars are formed in powerful and dusty starbursts of short duration, that have bolometric luminosities similar to the estimated bolometric luminosities of their obscured Seyfert 1 nuclei.
