CORSIKA 8 -- Contributions to the 37th International Cosmic Ray Conference in Berlin Germany (ICRC 2021)

TL;DR

CORSIKA 8 is a modular simulation framework for cosmic ray air showers, featuring validated cascades, a novel radio emission simulation framework, Cherenkov emission calculations, and detailed particle genealogy analysis.

Contribution

This paper introduces CORSIKA 8's new features, including a modular design supporting multiple emission models and detailed particle tracking capabilities.

Findings

Validated secondary hadron and electromagnetic cascades.

Developed a flexible radio emission simulation framework.

Demonstrated Cherenkov emission calculations with GPU support.

Abstract

Compilation of the six contributions to the ICRC conference 2021 by the CORSIKA 8 Collaboration. The status of the project is illustrated. In particular, the secondary hadron as well as the electromagnetic cascades are being validated individually, and current results are reviewed. A novel framework for radio emission simulations is presented, which is designed given the modular nature of CORSIKA 8 to support, both, the CoREAS as well as the ZHS formalism. At the same time, first Cherenkov emission calculations are shown which are based on CORSIKA 8 coupled with a GPU Cherenkov emission code. Finally, a new powerful feature of CORSIKA 8 is illustrated, where the entire genealogy of air shower particles can be studied in all details.
