F2a: Support to PCCP

Check out the project news!


  • The Paris Centre for Cosmological Physics is a place of research, education and scientific exchanges in the field of cosmology, or more generally the physics of the Universe. It was created in February 2010 by George F. Smoot, when he was hired as professor of the University Paris-Diderot and he saw the opportunity to create a large Parisian centre dedicated to cosmology.

    Supported from the start by University Paris Diderot, CNRS/IN2P3 and the Paris Observatory, PCCP aims at developing a synergy between the Parisian laboratories (at present APC, LPNHE, LUTh, GEPI, LPTENS) to enhance the contribution of the French community to the rapidly developing field of cosmology.

    LabEx UnivEarthS contributes to the financing of some of the actions of PCCP such as the organization of workshops, visitors and postdoctoral programs, but also the training of high school teachers and the conception of a general public MOOC to share a scientific adventure on the frontiers of the knowledge.
