    CTA - Cherenkov Telescope Array,
    an advanced facility for ground-based VHE gamma-ray astronomy


    The Cherenkov Telescope Array CTA is the next generation ground-based Very High Energy (VHE) gamma-ray instrument. Its objective is to explore in depth our Universe in VHE gamma-rays and investigate cosmic non-thermal processes, in close cooperation with observatories looking at other wavelength ranges of the electromagnetic spectrum, and with those using other messengers such as cosmic rays and neutrinos. With more than one hundred telescopes located in the northern and southern hemispheres, assuring full sky coverage, CTA will be the world's largest and most sensitive VHE gamma-ray observatory.

    The CTA Observatory will consist of three types of telescopes with different mirror sizes in order to cover the full energy range of interest; the design of the array foresees a factor of 10 improvement in sensitivity in the current VHE gamma-ray domain ranging from 100 GeV to some 10 TeV, and an extension of the accessible energy range from 20 GeV up to 300 TeV. Moreover, each CTA site will include highly-performance monitoring and calibration devices.

    The INAF/IASF-Palermo Institute strongly contributes to the CTA in several specific CTA areas as definition of array design, requirements, procedures and use cases, array calibration, simulation and analysis, science, speaker and publication office, as well as through the ASTRI Program.
