The vertical profile of atmospheric depth is an important element in extensive air shower studies. The depth of shower maximum is one of the most important characteristics of the shower. In the fluorescence technique of shower detection, the geometrical reconstruction provides the altitude of shower maximum, so that an accurate profile of atmospheric depth is needed to convert this altitude to ...

The runaway breakdown – extensive atmospheric shower discharge (RB EAS) excited in thunderstorm atmosphere by high energy cosmic ray particles (εp > 10 − 10 eV) generate very powerful radio pulse. The RB EAS theory is compared with observations of radio pulses. An agreement between the theory and experiment is established. The existence of nowaday satellite and ground based systems which obtain...

Simulations of radio emission from extensive air showers we have published so far were performed with a Monte Carlo code using analytical parametrisations to describe the spatial, temporal, energy and angular particle distributions in the air shower. A new version of our simulation code, which replaces these parametrisations with precise, multi-dimensional histograms derived from per-shower COR...

Since 2014, the University Campus of Hellenic Open (HOU) hosts Astroneu array which is dedicated to detection Extensive Air Showers (EAS) induced by high energy Cosmic Rays (CR). The incorporates 9 large particle scintillation detectors and 6 antennas sensitive in Radio Frequency (RF) range 1-200 MHz. are adjusted three autonomous stations operating an environment with strong electromagnetic ba...

We present measurements of the depth of maximum for extensive air showers (EAS) produced by cosmic ray nuclei with energies above 10eV. The air showers were observed using the University of Utah's Fly's Eye detectors operating in stereo mode. The data show an elongation rate of 69 ± 5 g/ cm per decade above 10eV before correction for triggering and resolution effects. These effects contribute a...

Based on CORSIKA and REAS2 simulations, we investigate the dependence of geosynchrotron radio emission from extensive air showers on the energy of the primary cosmic ray and the depth of the shower maximum. 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 electroma...
