Physicists from the CNRS and the University of Warsaw unveiled an instability at play in the primordial universe that modifies the theoretical interpretation of the cosmic microwave background observations, and which enables one to severely constrain scenarios of inflation built in fundamental physics. This work is published in Physical Review Letters. [more]
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 made major contribution to 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?

Ben Wandelt was named 2015 Fellow of the APS in recognition of his outstanding contributions to physics. [more]
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]
