Latin-American School on CTA Science

March 27-31, 2023

São Paulo, Brazil



The Cherenkov Telescope Array (CTA) will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific program of CTA is rather broad: from understanding the role of relativistic cosmic particles to the search for dark matter. CTA will explore the universe using photons from 20 GeV to 300 TeV and significantly improve the sensitivity of high-energy gamma-ray phenomena.

It will feature two arrays, a southern one being located at the European Southern Observatory (ESO) site in Chile, Atacama desert, and a northern one located at the Roque de los Muchachos Observatory (ORM) site in La Palma, Canary Islands. This combination will make CTA the first ground-based gamma-ray telescope with the capability to observe a large sky fraction. CTA will have telescopes of different sizes, with the large ones reaching 23 meters in diameter. The CTA consortium currently has 1,500 members from more than 150 institutes in 25 countries, 18 of them in Latin America.

Therefore, it is of paramount importance to train Latin-American students about CTA science, and this motivated the first Latin-American School of CTA Science. The school will feature lectures on the following topics:

  • Numerical Tools
  • Dark Matter
  • Fundamental Physics
  • Multi-Messenger.

The lectures will be given by experts on these topics who are familiar with the imaging atmospheric Cherenkov telescopes technique. At the school, the students will be familiarized with theoretical aspects of gamma-ray astronomy and through hands-on activities will learn how to install the codes and familiarize themselves with numerical programs, which are important for CTA science.

There is no registration fee and limited funds are available for travel and local expenses.
