Cosmic rays consist of particles, primarily nuclei, that enter the atmosphere of the Earth from space. When a cosmic ray collides with the nucleus of an atom in the air (most likely nitrogen or oxygen), a multiplicity of secondary particles is created, which can set of a cascade known as a cosmic air shower. Shower dominated by hadronic interactions are called hadronic showers. In high-energy hadronic collisions jets can occur as a result of the hard scattering, and these jets in cosmic air showers cause density fluctuations that can be detected using HisPARC detectors. Hans Montanus uses computer simulations to investigate this phenomenon.
