The IUPAP-TIFR Homi Bhabha Award (Certificate, Medal and Prize) was established by the International Union of Pure and Applied Physics (IUPAP) and the Tata Institute of Fundamental Research (TIFR), Mumbai, India in 2010 to honor Dr. Homi Jehangir Bhabha, a cosmic ray physicist well-known for the Bhabha-Heitler cascade theory and relativistic positron-electron scattering, also known as Bhabha scattering. Homi Bhabha founded the TIFR in 1945 and initiated the nuclear energy program in India in 1951 with strong support from the well-known philanthropist and industrialist JRD Tata and the Government of India then led by Prime Minister Jawaharlal Nehru. Homi Bhabha initiated experimental programs for the study of cosmic ray particles and their interactions with instruments either carried aloft to the top of the atmosphere with balloons or placed in laboratories at high altitude or deep underground. The Homi Bhabha Medal and Prize consists of a certificate, a medal, a significant monetary award and an invitation to visit the TIFR, Mumbai, and the Cosmic Ray Laboratory, Ooty to give public lectures there, and will be awarded biennially at the International Cosmic Ray Conferences (ICRCs), held generally in odd numbered years.

The IUPAP-TIFR Homi Bhabha Award will be given to an active scientist who has made distinguished contributions in the field of cosmic ray physics over an extended academic career. The winner of the prize will be selected by the members of the C4 and a senior cosmic ray scientist nominated by the Director, TIFR. The winner of the 2023 prize will be announced at the opening session of the 38th ICRC 2023, on 26 July 2023, and invited to visit India at a mutually convenient time thereafter to deliver two public lectures. The Director, TIFR will present the Homi Bhabha medal and the monetary award to the winner on this occasion. The winner will be provided with reasonable travel expenses and local hospitality for the visit to TIFR, Mumbai and Cosmic Ray Laboratory, Ooty in India.

Nominators are encouraged to consider nominating women and persons from minority backgrounds in line with the IUPAP objective of a better reflection of geographic and gender balance. Nominations should include a letter supporting the case, the nominee’s curriculum vitae, and a list of important publications. The sponsor may also wish to ask two co-sponsors to send separate letters supporting the nomination.

The deadline for the receipt of nominations is 10 March 2023.

Self-nominations will not be considered.

A list of the previous winners can be also found at the website of C4.
