International Cosmic Ray Conference

The ICRC conference series has been held biennially since 1947 by Commission C4 (Astroparticle Physics) of the International Union of Pure and Applied Physics (IUPAP*). The main topics covered by this conference are Cosmic Ray Physics, Gamma-Ray Astronomy, Neutrino Astronomy & Neutrino Physics, Dark Matter Physics, Solar and Heliospheric Physics, Multi-messenger Astronomy, and an additional new topic in the 2023 conference is Gravitational Wave Astronomy

The ICRC Conference Series has been organised biennially since 1947 under the auspices of the International Union of Pure and Applied Physics (IUPAP) and is the largest conference on Astroparticle Physics, bringing together the different topics of the field.

The main topics are Cosmic Ray Physics, Gamma-Ray Astronomy, Neutrino Astronomy & Neutrino Physics, Dark Matter Physics and Solar and Heliospheric Physics. Additional new topics in the 2021 conference are Multi-messenger Astronomy and Outreach & Education. Broad reviews and recent scientific results, related theory and modelling, experimental methods, techniques and instrumentation will be presented. The ICRC 2021 will be a prime forum to learn about news and developments in Astroparticle Physics and to appreciate the links between its topics.

The conference is jointly organised by the Local Organising Committee (LOC) with representatives of DESY and other German research labs and universities active in Astroparticle Physics, an independent International Scientific Program Committee (ISPC) and the IUPAP Commission C4 (Astroparticle Physics) as International Advisory Committee (IAC) .

Due to the COVID-19 pandemic, this ICRC, originally planned for Berlin, Germany, is being organized as an online conference.

The 36th International Cosmic Ray Conference, or ICRC 2019, is a physics conference organized biennially by the Commission on Astroparticle Physics (C4) of the International Union of Pure and Applied Physics (IUPAP) since 1947, where physicists from the world present the results of their research in Astroparticle Physics.

The meeting covers cosmic-ray physics, neutrino physics, gamma-ray astronomy, dark matter, particle astrophysics, and detector techniques in these fields.

This collection of the proceedings, in the intention of the editors, will provide a detailed state-of-the-art account of the status of the Astroparticle Physics topics discussed at the conference. We thank all the participants and contributors who made this possible.

At the ICRC 2019 open ceremony a public lecture was delivered by Prof. Alan Watson, from the University of Leeds.
