CTA Project: Building the world’s most advanced ground-based gamma-ray observatory

CTA Consortium: The CTA Consortium includes 1,500 members from more than 200 institutes in 31 countries.

CTA Science:  CTA will look at the sky in higher energy photons than ever measured before. 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 include:

  • CTA will have unprecedented accuracy and will be 10 times more sensitive than existing instruments
  • An energy resolution of 10 percent will improve CTA’s ability to look for spectral features and lines associated with the annihilation of dark matter particles
  • Rapid slewing in as low as 20 seconds will allow CTA to catch gamma-ray bursts ‘in the act’ of exploding
  • Energies as low as 20 GeV will allow CTA to probe transient and time-variable gamma-ray phenomena in the very distant universe with unprecedented precision
  • Energies up to 300 TeV will push CTA beyond the edge of the known electromagnetic spectrum, providing a completely new view of the sky and allowing us to search for extreme particle accelerators
  • A field of view of eight degrees will allow CTA to survey the sky much faster and measure very extended regions of gamma-ray emission
  • An angluar resolution approaching one arcminute will allow CTA to resolve many cosmic sources to understand how ultra-relativistic particles are distributed in and around these systems


CTA in Catania: National Institute for Astrophysics develop a prototype of Small Size Telescope at the Catania Astrophysical Observatory on Etna.
