This lecture was delivered in June 2015, by Roger Blandford, founding director of the Kavli Institute for Particle Astrophysics and Cosmology. Blandford explores how certain cosmic sources accelerate elementary particles to extremely high energies, beyond what we can produce on Earth. He explains how cosmic rays can be observed either directly or indirectly through the gamma rays they emit when interacting with the galactic environment, revealing extreme phenomena such as black holes, neutron stars, and energetic shocks. The lecture also presents the instruments and techniques used to study these emissions and discusses how these methods make it possible to connect high-energy observations with fundamental structures and processes in the universe.

This lecture is part of the astrophysics series ‘The Science of the Cosmos, the Science in the Cosmos’, tackles the fundamental questions in contemporary astrophysics.The fourth edition considers the enigmatic nature of dark matter and the most recent attempts to detect it with large underground instruments, the expansion of the universe, as well as recent research with particle accelerators.
