Joseph Silk

Premio Balzan 2011 per l'universo primordiale, dai primi istanti (tempo di Planck) alla formazione delle galassie

Per il lavoro pionieristico sulle prime fasi evolutive dell’Universo basato sullo studio degli effetti che processi e fenomeni fisici diversi – quali la materia oscura e la curvatura dello spazio – hanno avuto sulle fluttuazioni del fondo cosmico a microonde e sulla formazione di galassie di diverso tipo.

Biographical and Bibliographical Data

Joseph Ivor Silk, born in London, England, on 3 December 1942, is a British and a US citizen.

He is currently Professor of Physics at the Institut d’Astrophysique, Université Pierre et Marie Curie, Paris, Homewood Professor in the Department of Physics and Astronomy, Johns Hopkins University, Baltimore, and Senior Fellow in the Beecroft Institute of Particle Astrophysics and Cosmology, Department of Physics, University of Oxford.

He received his BA in Mathematics from Clare College, Cambridge, in 1963 and his PhD in Astronomy from Harvard University in 1968.
Fellow of the Institute of Theoretical Astronomy at the University of Cambridge from 1968 to 1969, he was a Research Associate at Princeton University from 1969 to 1970 and a member of the Institute for Advanced Study at Princeton from 1975 to 1976. He was Assistant Professor of Astronomy from 1970 to 1973, Associate Professor of Astronomy from 1973 to 1978, then Professor of Astronomy from 1978 to 1999 and Professor of Physics from 1988 to 1999 at the University of California, Berkeley. From 1999 to September 2011 he was Savilian Professor of Astronomy at the University of Oxford.

He was a Chercheur Associé at the Institut d’Astrophysique, Paris, from 1982 to 1983, in 1986, in 1987 and he has taken up again the position since 2000. He was also a Visiting Fellow of Mt. Stromlo and Siding Spring Observatories, Canberra, in 1999.
   He holds honorary degrees from the École Normale Supérieure de Lyon, the University of Rome “Tor Vergata” and the University Pierre & Marie Curie, Paris. He has given more than 330 invited conference lectures, primarily on galaxy formation, dark matter and cosmology.
