The Cherenkov Telescope Array (CTA) is the next-generation ground-based observatory for gamma-ray astronomy at very-high energies. CTA will be deployed in two sites, CTA-North in the Roque de los Muchachos observatory in the island of La Palma, and CTA-South in the Atacama desert, near the ESO Paranal observatory. With its unprecedented sensitivity, CTA will contribute to the understanding of the most extreme astrophysical environments in the universe, in which particles can be accelerated to ultra-high energies and produce gamma radiation via their interaction with ambient matter or radiation. CTA will also search for signatures of dark matter annihilation, and test Einstein’s theory of relativity by studying the propagation of very-high energy photons across cosmological distances.
CTA will observe the sky at an unprecedented very high energy. In fact, the cosmic particle accelerators CTA will probe can reach energies inaccessible to man-made accelerators like the Large Hadron Collider.
CTA’s unique capabilities will help us address some of the most perplexing questions in astrophysics. CTA will seek to understand the impact of high-energy particles in the evolution of cosmic systems and to gain insight into the most extreme and unusual phenomena in the Universe. CTA will search for annihilating dark matter particles and deviations from Einstein’s theory of relativity and even conduct a census of particle accelerators in the Universe.
