The Active Galactic Nuclei…..


Ongoing Activities:

  • The origin and early growth of the first supermassive black holes and their co-evolution with their host galaxies (Schneider, Valiante, Pezzulli)
  • The Luminosity Function of z>4 AGNs and their contribution to the Reionization (Giallongo, Fiore, Grazian)
  • Census of the non-local supermassive black holes and the obscured accretion contributing to the Cosmic X-ray Background via direct hard X-ray detection of AGNs in medium-deep extragalactic survey fields (Fiore, Zappacosta)
  • Co-evolution of galaxies and AGNs with semi-analytical models (Menci, Lamastra, Fiore, Giallongo)
