Abstract

Ultra High Energy Cosmic Rays are the most rare and energetic particles in the Universe, of which source origin, production mechanisms and type of primary particle we still don’t know yet. Because of this, the Pierre Auger Observatory became the world’s largest cosmic rays experiment on ground, where hundreds of researchers contribute worldwide to the physics studies of the most mysterious particles in the Universe, employing thus complementary innovative detectors on a large-scale in Argentina. Romania became full Auger member in 2014, being represented by 3 institutes presently, among which the host Institute of Space Science is represented by the project leader. The project comes in support of the local Auger group in order to contribute to the current upgrade of Auger detectors, where some are improved and some are extended, as the radio detector will cover the entire array of 3000 km2. The outcome of the project will be towards understanding of the radio detector response at large scale, for inclined events at very high energies, contribution to official simulation production in Auger GRID VO, and optimized simulations with a reduced list of candidate observers in order to accelerate time computing. The project will employ students from a complementary field, and will disseminate results accordingly, to increase the group visibility and science awareness, and support the continuity of research activity of the local group in Auger.

Project goal

The project aims to study the evolution of air showers, with closer look on the electrons and muons ratio, and the radio emission mechanisms of the registered radio signals, as well as the detector response at large-scale, i.e. AugerPrime RD, using HPC, distributed computing and intelligent algorithms to optimize the workflow of data analysis.

Research results

library of simulated and reconstructed events; software for data processing and analysis; server of storage for upgrading the ISS computational resources in Auger grid VO, talk/poster contribution in conferences/workshops; article/proceeding; education and outreach activities; internal note submitted to Auger; project’s web site; intermediate and final project reports.
