The Daniel Chalonge Medal 2012 has been awarded to Professor Brian SCHMIDT

The International Astrophysics School Daniel Chalonge has awarded the Daniel Chalonge Medal 2012 to Professor Brian P. Schmidt, Nobel Laureate of physics 2011 for his outstanding contribution to the discovery of the present accelerated expansion of the Universe, deeply discussed in the framework of the Chalonge School.

Brian Schmidt was lecturer in several courses of the School, and from the very beginning in the discovery of the acceleration of the Universe, which motivated the realization of very important projects in cosmology and the training and formation of young physicists and astrophysicists over the world.

The medal was presented to Brian Schmidt during the Open Session of the 16th Paris Cosmology Colloquium 2012 at the Observatoire de Paris HQ (historic Perrault building) in the Cassini Hall, on the meridian of Paris, which was attended by about hundred participants from the world over, among them four laureates of the Chalonge Medal: John Mather and George Smoot, Nobel laureates of physics, Anthony Lasenby and Peter Biermann.

The Chalonge Medal, coined exclusively for the Chalonge School by the prestigious Hotel de la Monnaie de Paris (the French Mint), is a surprise award and only nine Chalonge medals have been awarded in the 21 year school history.The list of the awarded Chalonge Medals is the following:

1991:Subramanyan Chandrasekhar, Nobel prize of physics. 1992: Bruno Pontecorvo. 2006: George Smoot, Nobel prize of physics. 2007: Carlos Frenk. 2008: Anthony Lasenby. 2008: Bernard Sadoulet. 2009: Peter Biermann. 2011: John Mather, Nobel prize of physics. 2012: Brian Schmidt, Nobel prize of Physics.

With the Chalonge Medal, the International School of Astrophysics Daniel Chalonge confirms its great appreciation to Dr. Brian Schmidt and his huge contribution to the construction of the Standard Model of the Universe, at the center of the Chalonge School programmes. This recognizes the outstanding scientific value and impact of the discovery of the dark energy component, compatible with the cosmological constant, which constitutes about three quarters of the content of the Universe.
