The 2019 ICTP Prize in honour of Subrahmanyan Chandrasekhar was awarded to Dr. Basudeb Dasgupta, Tata Institute of Fundamental Research, Mumbai, India and Dr. Suvrat Raju, International Centre for Theoretical Sciences, TIFR, Shivakote, Bengaluru, India. The 2019 ICTP Prize Ceremony, postponed from April 2020 due to the Covid-19 pandemic, will now take place on Wednesday 2 June 2021 at 11.30 hrs (CET/Trieste) in a hybrid format. The prize recognises Professor Basudeb Dasgupta (India) for innovative theoretical contributions to neutrino and dark-matter physics, especially to the understanding of collective neutrino oscillations. Dasgupta pioneered the field of collective neutrino flavor evolution in extreme astrophysical environments, such as those in supernovae, which helped the understanding of these spectacular and phenomenologically rich events. The prize recognises Professor Suvrat Raju (India) for new insights into the holographic description of black-hole interiors, for clarifying the nature of subtle non-local effects in quantum gravity, and for contributions to the study of the AdS/CFT correspondence. The feature article on the 2019 ICTP Prize winners is at: Each year, the ICTP Prize is given in honour of a scientist who has made outstanding contributions to the field in which the prize is given. The 2019 ICTP Prize is given in honour of Subrahmanyan Chandrasekhar. Born on 19 October 1910 in Lahore, Punjab, British India, Chandrasekhar is one of the most renowned and prolific Indian scientists. He worked on a great variety of subjects, making groundbreaking discoveries in different fields. He was awarded the 1983 Nobel Prize in Physics for "theoretical studies of the physical processes of importance to the structure and evolution of the stars". He died on 21 August 1995. The titles and abstracts of the Prize Lectures are given below. All are welcome to participate. The event will be livestreamed from the ICTP website.

The detailed programme outline for the Prize Ceremony is now available (see top left column). * Abstract for the Prize Lecture by Professor Basudeb Dasgupta on "Dying Stars, Dancing Neutrinos, and Us": Heavy stars end their lives in a supernova explosion, where about 10^57 neutrinos and antineutrinos are emitted over 10 seconds. These neutrinos perform an unusual and intricate dance -- repeatedly changing their flavor in a synchronized manner over nanoseconds -- as they leak out of the star. The rich and complex physics of this many-body quantum phenomenon affects the stellar explosion and the creation of vital chemical elements. In this talk, I will walk you through what we have learnt over the past two decades, what questions remain unanswered and how we, neutrino astronomers and astroparticle physicists, hope to unravel these mysteries. * Abstract for the Prize Lecture by Professor Suvrat Raju on "The Principle of Holography of Information": We will argue, using only broad physical principles, that any theory which combines quantum mechanics and gravity must have the property that information that is available on the bulk of a Cauchy slice is also available near the boundary of the slice. When applied to spacetimes with a negative cosmological constant, this approach sheds light on the origins of the AdS/CFT duality. It also indicates how holography should work for four-dimensional asymptotically flat spacetimes and has interesting implications for black holes.
The 2019 ICTP Prize Ceremony will take place in conjunction with ICTP's Summer School on Particle Physics which runs from 31 May to 11 June 2021.
