The data collected with the Pierre Auger Observatory have led to a number of surprising discoveries. While a strong suppression of the particle flux at the highest energies has been established unambiguously, the dominant physics processes related to this suppression cannot yet be identified. Within the energy range covered by fluorescence detector observations with sufficient statistics, an...

The Telescope Array (TA), located in Utah, USA, observes highest energy cosmic rays using Surface Detectors (SDs) and Fluorescence Detectors (FDs). The SD array consists of 507 scintillation detectors on a 1.2-km square grid covering 700 km^2. The FD sets located at three sites look over the surface array. Using the first 6-year data collected by the surface detectors, we found a cluster of...

IceTop is the 1 km^2 surface array of the IceCube Neutrino Observatory. Measurements of ground level particles by IceTop have been used for high precision measurements of the cosmic ray spectrum for energies of 3-300 PeV. Composition has been studied by considering coincident measurements of TeV muon bundles in the 2 km deep IceCube neutrino detector. Including IceTop data for GeV muons may...

The Extreme Universe Space Observatory (EUSO) to be accommodated in the
Japanese Experiment Module (JEM) of the International Space Station (ISS), JEM-EUSO,
is designed to discover the origin of ultrahigh energy cosmic rays by
observing extremely energetic extensive airshowers from space. The JEM-EUSO
design is based on a wide field of view (60$^o$) refractor with an ultrafast 0.3 M...

JEM-EUSO, on board the International Space Station, is a mission that aims at unveiling the nature and the origin of the ultra high energy cosmic rays (UHECRs), and to address basic problems of fundamental physics at extreme energies. The instrument is designed to measure the arrival direction, the energy and, possibly, the nature of these particles. It consists of a wide-field of view...

We present a concept for large area, low-cost detection of ultra-high energy cosmic rays (UHECRs) with a Fluorescence detector Array of Single-pixel Telescopes (FAST), addressing the requirements for the next generation of UHECR experiments. In the FAST design, a large field of view is covered by a few pixels at the focal plane of a mirror or Fresnel lens. We report first results of a FAST...
