The Mystery of High-Energy Cosmic Rays

An active galactic nucleus (AGN) containing a black hole, a possible source of high-energy cosmic rays.

Scientists love a mystery, because solving a mystery in nature means the opportunity to learn something new about the universe. High-energy cosmic rays are just such a mystery. Something out there - no one knows what - is hurling incredibly energetic particles around the universe. Do these particles come from some unknown superpowerful cosmic explosion? From a huge black hole sucking stars to their violent deaths? From colliding galaxies?

Online Analysis of Pierre Auger Data with VISPA

Auger Skymap

With the VISPA internet platform you can perform physics analyses with the Pierre Auger public data in the web browser. Begin with a sky map of cosmic rays in an example analysis. Then, you can develop your own ideas and visualise the scientific results. To visualize cosmic nuclei propagating in our universe use the CRPropa simulation program.
