The Pierre Auger Observatory, in Argentina, is the present flagship experiment studying ultra-high energy cosmic rays. Facing the challenge due to low cosmic ray flux at the highest energies, the Observatory has been taking data since more than a decade, reaching an exposure of over 50 000 km2 sr yr. The combination of a large surface detector array and fluorescence telescopes provides a...

The Telescope Array (TA) is a hybrid experiment observing ultrahigh energy cosmic rays in the northern sky. Three fluorescence stations each view 108 degrees in azimuth and up to 30 degrees in elevation. They are located at the periphery of a ground array consisting of 507 plastic scintillator counters, of 1.2km spacing, and covering over 700 square kilometers. We will present the cosmic...

High-energy cosmic rays, impinging on the atmosphere of the Earth initiate cascades of secondary particles, the extensive air showers. The electrons and positrons in the air shower emit electromagnetic radiation. This emission is detected with the LOFAR radio telescope in the frequency range from 30 to 240 MHz.
The data are used to determine the properties of the incoming cosmic rays. The...

VERITAS is an array of four imaging atmospheric Cherenkov telescopes near Tucson, Arizona and is one of the world's most sensitive detectors of very high energy (VHE: >100 GeV) gamma rays and cosmic rays. The scientific reach of VERITAS covers the study of both Extragalactic and Galactic objects and the search for astrophysical Dark Matter. In this talk I will discuss the status of VERITAS...
