Radio emission simulations using CORSIKA 8 — •Nikos Karastathis¹, Remy Prechelt², and Tim Huege^1,3 for the CORSIKA 8 collaboration — ¹Institute for Astroparticle Physics, Karlsruhe Institute of Technology, Karlsruhe, Germany — ²Department of Physics and Astronomy, University of Hawaii-Manoa, Hawaii, USA — ³Astrophysical Institute, Vrije Universiteit Brussel, Brussels, Belgium

For years, CORSIKA has served the scientific community as one of the leading simulation tools for air showers. Simulations of the radio emission from air showers are made possible within this context using the CoREAS extension. Given that the current code rests upon the monolithic structure of FORTRAN77, a complete reimplementation of CORSIKA 8 that is based on a modular and more flexible C++ design is an ongoing project. Part of this effort is to include radio-emission calculations as an integral part of the program.

In this talk, I will present the current state of the software design and how a reimplementation of CoREAS fits into CORSIKA 8 by taking advantage of its features. This design makes radio calculations more general, giving the freedom to choose different formalisms for the radio-emission calculations, such as the Endpoint or ZHS formalisms, and in the future accommodating more complex interaction media. Our first radio simulations using CORSIKA 8 will be presented.
