Des physiciens du CNRS et de l’université de Varsovie ont mis à jour un phénomène d'instabilité à l'oeuvre dans l'univers primordial qui modifie l’interprétation théorique des observations du fond diffus cosmologique, et permet de contraindre fortement les scénarios d'inflation construits dans le cadre de la physique fondamentale.

Luc Blanchet, senior researcher in theoretical physics at IAP/ILP, is one of the laureates of the "Special Breakthrough Prize In Fundamental Physics" awarded for the detection of gravitational waves, confirmation of the prediction by Albert Einstein a hundred years ago. Luc Blanchet is especially involved in the theoretical calculation of the gravitational waveform generated by the coalescence of neutron stars or black holes.

Cosmology@Home attempts to answer this big question and just released a new exciting app to do so! This app (called "planck_param_sims") uses data from the Planck satellite and allows anyone to contribute to their current analysis.
The one sentence summary of this tool is that its sort of like turning contributing computers (yours?) into mixer boards and playing DJ with the echoes of the Big Bang! So what exactly does that mean, and how these results contribute to science?

Cosmic voids are fascinating for several reasons. For example, they were the first places in the Universe to be dominated by dark energy. They make up the majority of the volume of the Universe today and constitute an exceptional source of cosmological information. [more]
The Planck team released this image of the first all-sky observations of polarized light emitted by interstellar dust in the Milky Way. Planck member Paul Sutter helped create this visualisation of galactic magnetic field lines at the Lagrange Institute. [more]
