International Cosmic Ray Conference

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

• Cosmic Ray Physics,
• Gamma-Ray Astronomy,
• Neutrino Astronomy,
• Dark Matter Physics,
• Multi-Messenger Astrophysics,
• Solar and Heliospheric Physics,
• Astroparticle Physics Theory and Models,
• Experimental Methods, Techniques and Instrumentation and
• Outreach & Education in Astroparticle Physics.

As part of the opening ceremonies, The O'Ceallaigh Medal is presented to a researcher who has made distinguished contributions to Cosmic Ray Physics. Also, the Yodh Prize and the Bhabha Medal and Prize are awarded to senior members of the community.

For young researchers, the Shakti Duggal Award and two IUPAP Young Scientist Awards are presented at each ICRCs.

Proceedings are published for each conference. Some are, partially or in full, available online (see external links). The NASA's Astrophysics Data System (ADS) has started to gather these proceedings and publish them online on the ADS webserver.
