In my talk I will present DLCQ procedure and explain how it can be generalized to some special IIA backgrounds, Singular Homogeneous Plane-Waves. These space-times can be seen as Penrose limits of a very large class of metrics, including the Friedmann-Robertson-Walker cosmological model, so a non-perturbative string theory model such as that provided by DLCQ can hopefully teach us something...

The Pierre Auger Observatory was designed to make precise measurements of cosmic ray air showers induced by the highest energy cosmic particles. The aparatus consists of about 1600 water Cherenkov tanks distributed over an area of some 3000 square kilometers, all of which are overlooked by 24 fluorescence telescopes. The instrument has already provided us with the most detailed energy spectrum...
