DESCRIPTION:Speakers: Jorge Otero Santos\n\nThe gamma-ray extragalactic sk
 y is dominated by blazars\, radio-loud active galactic nuclei (AGN) with r
 elativistic jets that are closely aligned with our line of sight. In the M
 eV range\, the Fermi-LAT satellite has led the efforts in studying this vi
 olent type of sources\, with more than 3000 known blazars discovered so fa
 r in the MeV range. In the GeV-TeV range\, the Cherenkov experiments MAGIC
 \, HESS and VERITAS have made significant advances in the field. However\,
  their sensitivity has only allowed us to discover ~300 sources in the mos
 t extreme Universe after two decades of operations\, with only ~90 being A
 GN and blazars.\n\n \nThe Cherenkov Telescope Array Observatory (CTAO) st
 ems as the future of ground-based gamma-ray astronomy. Its improved capabi
 lities promise to revolutionize the field in the near future. Its first te
 lescope\, the Large-Sized Telescope prototype (LST-1)\, is already operati
 ng in La Palma (Spain) since 2018\, therefore being not only the future bu
 t also the present in the field. In this talk I will give an overview of s
 ome of the first scientific results on AGN and blazars obtained during LST
 -1’s first years of operation. The seminar will conclude with a discussi
 on of future perspectives with the fully operating CTAO.\n\n\nhttps://indi
