Studies of the Cosmic Ray Composition with the Pierre Auger Observatory

Seminar
Tuesday, 18.05.2010 14:00 to 16:00

Speakers: Michael Unger (Forschungszentrum Karlsruhe, Institut für Kernphysik, Karlsruhe)
Place: Room 117, 1st floor, building of the Institute of Physics AS CR, Na Slovance 2, Praha 8
Presented in English
Organisers: Division of Elementary Particle Physics
In the talk we will discuss the the cosmic ray composition of extra galactic cosmic rays and describe the close connection of air shower observables and ultra high energy hadronic interactions. After a short introduction to the Pierre Auger Observatory the study of the composition of ultra high energy cosmic rays with energies above 1018 eV using the fluorescence telescopes of the observatory will be presented.
