The O'Ceallaigh Medal was established by the estate of the late Prof. Cormac O'Ceallaigh and the Dublin Institute for Advanced Studies to honour "outstanding contributions to cosmic ray physics" and is awarded by the IUPAP Commission on Cosmic Rays. The Commission wishes to use this award to recognize significant contributions to our field over an extended career. The selection will be made by a subcommittee of the IUPAP C4 Commission.
