We present a measurement of the cosmic-ray spectrum above 100 PeV using the part of the
surface detector of the Pierre Auger Observatory that has a spacing of 750 m. An inflection of …

We report a measurement of the flux of cosmic rays with unprecedented precision and
statistics using the Pierre Auger Observatory. Based on fluorescence observations in …

We report a measurement of the energy spectrum of cosmic rays above 2.5× 10 18 eV
based on 215 030 events. New results are presented: at about 1.3× 10 19 eV, the spectral …

We present an update of the cosmic ray energy spectrum measured from $3 {\times} 10^{17}
$ eV to over $10^{20} $ eV at the Pierre Auger Observatory. This energy range is covered by …

The energy spectrum of ultra-high energy cosmic rays measured using the Pierre Auger
Observatory is presented. The measurements benefit from the huge exposure of …

We report a measurement of the energy spectrum of cosmic rays for energies above 2.5× 10
18 eV based on 215,030 events recorded with zenith angles below 60°. A key feature of the …

The knee in the all-particle energy spectrum is scrutinized with a phenomenological model,
named poly-gonato model, linking results from direct and indirect measurements. For this …

A measurement of the cosmic-ray spectrum for energies exceeding $4 {\times} 10^{18} $ eV
is presented, which is based on the analysis of showers with zenith angles greater than …

The energy spectrum of cosmic rays between 1016eV and 1018eV, derived from
measurements of the shower size (total number of charged particles) and the total muon …

Abstract The Telescope Array (TA) experiment is the largest detector to observe ultra-high-
energy cosmic rays in the northern hemisphere. The fluorescence detectors at two stations …
