    • Abstract

       

      In this work, the effects of extensive air showers (EASs) were described by estimating the lateral distribution function (LDF) at very high energies of various cosmic-ray particles. The LDF simulation was performed using the air shower extended simulation (AIRES) system version 2.8.4a. LDF was simulated forcharged particles such as pair production, muons, and all charged particles at very high energies (10$^{16}$, 10$^{18}$, and 10$^{19}$ eV). The effect of primary particles, energies, and zenith angle ($\theta$) on the LDF of the charged particles produced in the EAS was taken into account. The LDF simulation of the charged particles was compared with the experimental results and found to be in good agreement with the pair production and muon particles in energies of 10$^{18}$ and 10$^{19}$ eV for $\theta = 10^{\circ}$. LDF parameterization of charged secondary particles (electrons and positrons) and secondary muon particles, initiated by primary proton and iron nucleiat the energy 10$^{19}$ eV, was performed. On the basis of this simulation, sets of approximating functions for primary protons and iron nuclei for vertical showers were obtained.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
