n recent years gamma-ray observations have significantly advanced our understanding of acceleration processes at work in Supernova remnants. Unprecedented morphological studies of TeV gamma-ray emission from shell-type Supernova remnants have shown a striking correlation to X ray emission. Energy spectra of up to 100~TeV confirm particle acceleration close to the ``knee'' in the Cosmic ray...

The High-Altitude Water Cherenkov (HAWC) Observatory is designed to observe extensive air showers produced by cosmic rays and gamma rays between 50 GeV and 100 TeV. HAWC is unique among TeV detectors because it can be used to observe air showers from a wide range of arrival directions, enabling us to perform a synoptic survey of the TeV sky. HAWC is also designed to have a high livetime...

LOFAR is a multipurpose radio telescope which can be used for radio detection of cosmic rays while running astronomical observations at the same time. The core of LOFAR contains 2300 antennas within an area of four square kilometer. This high density makes it an ideal location for a detailed study of the radio signal of extensive air showers in the energy range 10$^{16}$ - 10$^{18}$ eV.

The longitudinal development of an extensive air shower reaches its maximum at a depth, Xmax, that depends on the species of the primary cosmic ray.
Using a technique based on Xmax, we measure the cosmic-ray mass composition from analyses of 3.7 years of monocular-mode operation of the newly constructed fluorescence detectors of the Telescope Array experiment.

IceTop, the surface component of the IceCube detector, has mea-
sured the energy spectrum of cosmic ray primaries in the range be-
tween 1.58 PeV and 1.26 EeV. This measurement was done by sam-
pling the lateral distribution function at distances from the shower axis
where the signal does not depend strongly on systematic variations in
the muon content of the air showers. Since May 2010,...
