[GA145] Extragalactic source population studies at very high energies in the Cherenkov Telescope Array era

The Cherenkov Telescope Array (CTA) is the next generation ground-based gamma-ray observatory. It will provide an order of magnitude better sensitivity and an extended energy coverage, 20 GeV--300 TeV, relative to current experiments. Imaging Atmospheric Cherenkov Telescopes (IACTs), despite featuring an excellent sensitivity, are characterized by a limited field of view which makes the blind search of new sources extremely time inefficient. Fortunately, the Fermi-LAT collaboration recently released a new catalog of about 1600 sources that describes the full sky at energies above 10 GeV (the 3FHL catalog), currently being the most appropriate description of the sky that will be accessible to CTA. In this presentation, we discuss a detailed analysis of the extragalactic source population (mostly blazars) that will be studied by CTA in the near future using simulations based on its latest expected configuration and on the data reported by the 3FHL catalog. Also, we propose strategies to optimize the observation time for follow-up campaigns and different scientific goals.
