A simple analytical argument is proposed for a possible explanation of the characteristics lateral shower age (s) proton (p)/nuclei-initiated showers. The states that density distribution (LDD) electrons p-initiated due to superposition several electromagnetic (EM) sub-showers developed at very early stage in atmosphere from decay neutral pions ( $$\pi ^{0}$$ s). Thanks property electron LDD p ...

Abstract We explore the sensitivity offered by a global network of cosmic-ray detectors to novel, unobserved phenomenon: widely separated simultaneous extended air showers. Existing localized observatories work independently observe individual showers, offering insight into source and nature ultrahigh-energy cosmic rays. However no current observatory is large enough provide anticipated process...

It is shown that using the observed extensive air shower (EAS) electron and truncated muon size spectra at sea level one can solve the EAS inverse problem reconstruction of primary energy spectra and elemental composition, for not more than 2 kinds of primary nuclei. ∗e-mail:[email protected]

We propose to extract the charge information of high energy muons in very inclined extensive air showers by analyzing their relative lateral positions in the shower transverse plane. We calculate the muon lateral deviation under the geomagnetic field and compare it to dispersive deviations from other causes. By our criterion of resolvability, positive and negative muons with energies above 104 ...

Interpretation of EAS measurements strongly depends on detailed air shower simulations. The uncertainty in the prediction of shower observables for different primary particles and energies is currently dominated by differences between hadronic interaction models. The new models QGSJET II-3 and EPOS 1.6, which reproduce all major results of existing accelerator data (including detailed data of R...

The pattern of the radio emission of air showers is finely sampled with the LowFrequency ARray (LOFAR). A set of 382 measured air showers is used to test a fast, analytic parameterization of the distribution of pulse powers. Using this parameterization we are able to reconstruct the shower axis and give estimators for the energy of the air shower as well as the distance to the shower maximum.

Shower heads and hot-water faucets containing Legionella pneumophila were evaluated for aerosolization of the organism with a multistage cascade impaction air sampler. Air was collected above two shower doors and from the same rooms approximately 3 ft (91 cm) from the shower doors while the hot water was running. Low numbers (3 to 5 CFU/15 ft3 [0.43 m3] of air) of L. pneumophila were recovered ...
