The International Particle Physics Group (IPPOG) is a global network active in informal education and outreach particle physics related research, including cosmic-ray astro-particle physics. Since many years, IPPOG has been actively supporting the Cosmic Day organized by DESY Muon Week Quarknet. In 2015 started work on establishing universal portal through which successful study programmes can reach out to teachers students around world. This common web platform being developed frame of its...
When a cosmic ray enters the Earth’s atmosphere, an avalanche of (charged) particles is created, which called air shower. Charged passing through magnetic field emit electromagnetic radiation that can be detected by ground-based dipole antennas. The southern site Pierre Auger Observatory, located in Argentina, provides excellent environment for testing various prototype radio detectors cosmic-ray studies. first results will discussed. events obtained used to characterize signal showers. this...
The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles cosmic origin, with energies in excess 100 PeV. GRAND uses large surface arrays autonomous radio-detection units to look the radio emission from extensive air showers that are triggered by interaction rays, gamma and neutrinos atmosphere or underground. In particular, neutrinos, future final phase aims be sensitive enough discover them spite their plausibly tiny flux. Presently,...
