Recent results from the KASCADE extensive air shower experiment are presented. After briefly reviewing the status of the experiment we report on tests of hadronic interaction models and emphasize the progress being made in understanding the properties and origin of the knee at eV. Analysing the muonand hadron trigger rates in the KASCADE calorimeter as well as the global properties of high ener...
A new approach to simulate fluorescence photons produced in extensive air showers is described. A Monte Carlo program based on CORSIKA produces the fluorescence photons for each charged particle in the development of the shower. This method results in a full three-dimensional simulation of the particles in a shower and of the fluorescence light generated in the atmosphere. The photons produced ...
KASCADE-Grande is a large detector array for observations of the energy spectrum as well as the chemical composition of cosmic ray air showers up to primary energies of 1 EeV. The multi-detector arrangement allows to measure the electromagnetic and muonic components for individual air showers. In this analysis, the reconstruction of the all-particle energy spectrum is based on the size spectra ...
In this work, charm production in the dpmjet hadronic jet simulation is compared to experimental data. Since the major application of dpmjet is the simulation of cosmic ray-induced air showers, the version of the code integrated in the CORSIKA simulation package has been used for the comparison. Wherever necessary, adjustments have been made to improve agreement between simulation and data. Wit...
Abstract Some simple arguments are introduced for a possible explanation of the behavior lateral shower age proton-initiated showers. The corresponding analytical treatment based on proposed argument is then illustrated. Using Monte Carlo simulation (MC) code CORSIKA, we have validated how different characteristics associated with predicted in present parametrization, can be understood. and its...

We present here a comparison of interaction models commonly used for simulating cosmic ray shower development in the atmosphere at energies greater than 1 TeV. The implementations of these models in CORSIKA and the FLUKA transport and interaction code are relevant for extensive air shower experiments, neutrino telescopes, and gamma-ray surfacebased detectors. We compare the pion, kaon, charmed ...
In the absence of a standard source of gamma rays or hadrons of known energy one has to study the details of production of Čerenkov light at the observation level only through detailed simulation studies. Recently such studies have become all the more important in view of the various techniques resulting from such studies, to distinguish between gamma ray initiated events from those generated b...
Based on CORSIKA and REAS2 simulations, we investigate the sensitivity of geosynchrotron radio emission from extensive air showers to the primary cosmic ray energy and mass. It is found that at a characteristic lateral distance, the amplitude of the bandpass-filtered radio signal is directly proportional to the energy deposited in the atmosphere by the electromagnetic cascade, with an RMS uncer...
