The next European cosmology mission starts construction
The space mission EUCLID, intended to map the universe in order to understand the influence of dark matter and dark energy, just passed the implementation phase. The EUCLID mission of the European Space Agency (ESA), involving scientists from CEA-IRFU, is to be launched in 2020 by a Soyuz Russian rocket. It aims to measure the position and shape of over a billion galaxies up to distances of ten billion light years.

First successes in forecasting solar flares
Researchers at the Center for Theoretical Physics (CNRS / Ecole Polytechnique) and Astrophysics Department-Laboratory AIM (CNRS / CEA / Université Paris Diderot) have identified a key phenomenon in the emergence of solar flares. Using satellite data and numerical modeling, the researchers were able to follow the evolution of the solar magnetic field in a specific area of the Sun that gave rise to a flare.

Progress and involvement of the CEA into this chinese and french space mission
2014 has been a fruitful year for SVOM (Space-based multiband astronomical Variable Objects Monitor), a chinese and french space mission dedicated to the study of gamma-ray bursts. The decisions taken at the highest level, the governments in March and the respective space agencies in August, restart the project after a frozen period. As a direct result, two important meetings of the consortium (kick-off meeting) took place in September, one at CNES in Toulouse and the other at Shanghai.

A new method for the reconstruction of the finest details
Using the latest data from the Planck and WMAP satellites, the laboratory CosmoStat (LCS) of CEA-IRFU just provides the most complete and accurate picture of the diffuse microwave background of the universe considered to be the primary light emitted at the beginning of the expansion. The new map of the diffuse background was built thanks to a new method of separating components called LGMCA particularly well suited to the separation of galactic foregrounds that blur the background image.
