Prix Balzan 2011 pour l'univers primordial (du temps de Planck jusqu'aux premières galaxies)

Pour son travail de pionnier sur les premières phases de l’évolution de l’univers à partir de l’étude des effets que différents processus et phénomènes physiques – comme la matière noire et la courbure de l’espace – ont sur les fluctuations du rayonnement du fond cosmologique et sur la formation de galaxies de différents types.

Federal Councillor,
Chairman of the Balzan Foundation,
Ladies and Gentlemen, 

I cannot overstate the great joy that I felt when I heard the news that I had been awarded the 2011 Balzan Prize. My feelings were shared between my role and the contributions of my many collaborators without whom my work would have been far less significant. 

I began my studies of the early universe and predicted the imprint of galaxy formation on the fossil radiation as a graduate student at Harvard. My timing was impeccable, as the cosmic microwave background radiation had just been discovered. But the significance of my early work was greatly amplified in joint studies with my numerous graduate students and postdoctoral fellows, who worked with me over many years when I was teaching at the University of California at Berkeley. I went on to the University of Oxford, to whom I am grateful for providing me with ideal conditions for research by establishing the Beecroft Institute for Particle Astrophysics and Cosmology.

Research at the frontiers of knowledge is like planting a garden in arid land. It needs constant nurture and encouragement. Oxford provided a fertile environment, and New College a social and interdisciplinary spline that facilitated scientific interactions. 

I am delighted to acknowledge the hospitality of my current institutions, the Institut d’Astrophysique of the Université Pierre et Marie Curie and the Department of Physics and Astronomy at the Johns Hopkins University, in providing a new and stimulating setting for my research. 
I finally wish to express my deepest gratitude to the Balzan Foundation and its General Prize Committee for this tremendous honour, and to my family for their continuing support and patience.
