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.

Detection prospects for the Cosmic Neutrino Background using laser interferometers

Valerie Domcke, Martin Spinrath

2017-04-11

The cosmic neutrino background is a key prediction of Big Bang cosmology which has not been observed yet. The movement of the earth through this neutrino bath creates a force on a pendulum, as if it was exposed to a cosmic wind. We revise here estimates for the resulting pendulum acceleration and compare it to the theoretical sensitivity of an experimental setup where the pendulum position is measured using current laser interferometer technology as employed in gravitational wave detectors. We discuss how a significant improvement of this setup can be envisaged in a micro gravity environment. The proposed setup could simultaneously function as a dark matter detector in the sub-MeV range, which currently eludes direct detection constraints.
