Measurements of the energy spectrum, the arrival directions and the mass composition.
Searches for high energy photons, neutrons, neutrinos and high energy magnetic monopoles.
Summary
The Pierre Auger Observatory is being detecting high energy cosmic rays since 2004. A total of 1500 ground particle detectors are distributed over an area of 3000 km$^{2}$ in the "Pampas" of Argentina. Additionally, 5 fluorescence telescope sites measure the energy deposited in the atmosphere by the interacting energetic comic ray. We have been able to measure, with an unprecedented statistics, the cosmic rays energy spectrum from energies as low as 10$^{17}$ eV up to 10$^{20}$ eV. We have accumulated enough statistics to measure very small large scale anisotropies on their arrival directions. Our most intriguing results are perhaps the indications that at higher energies (above 3$\times$10$^{18}$ eV) cosmic rays appear to be dominated by heavier nuclei. We have also searched for high energy photons, neutrons, neutrinos, and even high energy monopoles. In this presentation I will summarize the latest status of our measurements.
