In this presentation we will discuss measurements of the longitudinal development of air showers at the Pierre Auger Observatory. The longitudinal development can be directly observed by the fluorescence telescopes of Auger and we will present the results on the evolution of the average of the shower maximum and its fluctuations as a
function of energy. Moreover, two observables from the...

In order to clarify the origin of ultra high energy cosmic rays (UHECRs),
it is very important to determine the mass composition.
The most effective strategy to determine the mass composition is
Xmax technique.
Xmax is the atmospheric depth of air shower maximum measured by
fluorescence detectors (FDs).
HiRes has reported Xmax measurement by FDs which indicated
proton dominated mass...
