Description
The Cherenkov Telescope Array Observatory (CTAO) will be the next-generation facility for very-high-energy gamma-ray astronomy, covering the energy range from ~20 GeV to 300 TeV and improving sensitivity by at least an order of magnitude over current instruments. It will be the first gamma-ray open, proposal-driven observatory. With observation stations in La Palma (North) and near ESO Paranal (South), CTAO will provide full-sky coverage and unprecedented capabilities for the study of cosmic accelerators, transient phenomena, and extreme astrophysical environments.
In this contribution, I will present an overview of CTAO, its key scientific goals, expected performance, and the current status of construction and preparation for initial operations, including prospects for the start of early science within the next two or three years. I will then highlight its strong scientific connections with the ESO facilities. Joint observation programmes will enable transformative studies of cosmic rays, star-forming regions, the Galactic Centre, relativistic jets, and explosive transients. In the evolving multi-wavelength and multi-messenger landscape, this synergy will be essential to fully realise the shared scientific potential of CTAO and ESO.
