Selected Press Releases and Media Coverage

  • EU-funded researchers have helped generate the most accurate map to date of dark matter, the mysterious substance that makes up 80 % of the universe. The innovative big-data technologies they used will have a significant impact on fields as diverse as astrophysics and biomedical imaging.

  • Big Data could hold the key to some of the most complex phenomena described in science – provided that we can make sense of its dizzying quantities of information. The DEDALE project developed algorithms enabling just that and used them to measure the amount of dark matter in the universe.

  • CosmoStat members in collaboration with colleagues at University College London (UCL)  have significantly improved the analysis of dark matter maps in the Universe with new methods of data analysis (GLIMPSE method).  

  • Philippe Ciuciu et Jean-Luc Starck expliquent leur rencontre et la génèse de leur projet COSMIC,  financé par le mécanisme DRF Impulsion de la direction de la recherche fondamentale du CEA depuis 2016.  

  • Managing the huge volumes and varying streams of Big Data digital information presents formidable analytical challenges to anyone wanting to make sense of it. Consider the mapping of space, where scientists collect, process and transmit giga-scale data sets to generate accurate visual representations of millions of galaxies. Or consider the vast information being generated by

  • The new international projects, such as the Euclid space telescope, are ushering in the era of Big Data for cosmologists. Our questions about dark matter and dark energy, which on their own account for 95% of the content of our Universe, throw up new algorithmic, computational and theoretical challenges. The fourth concerns reproducible research, a

  • La Direction de la recherche fondamentale au CEA lance le projet COSMIC, né du rapprochement de deux compétences en traitement des données localisées à l’Institut des sciences du vivant Frédéric-Joliot (NeuroSpin) et au CEA-Irfu (CosmoStat). Les mécanismes d’acquisition de données en radio-astronomie et en IRM présentent des similarités. Les modèles mathématiques utilisés sont en effet

  • ​A key challenge in cosmological research is how to extract the most important information from satellite imagery and radio signals. The difficulty lies in the systematic processing of extremely noisy data for studying how stars and galaxies evolve through time. This is critical for astrophysicists in their effort to gain insights into cosmological processes such

  • Today marks the release of the first papers to result from the XXL survey, the largest survey of galaxy clusters ever undertaken with ESA’s XMM-Newton X-ray observatory. The gargantuan clusters of galaxies surveyed are key features of the large-scale structure of the Universe and to better understand them is to better understand this structure and

  • In a review article in “Reports on Progress in Physics”, Martin Kilbinger of Astrophysics Department – AIM Laboratory at CEA-IRFU presents a comprehensive assessment of the results obtained from observations of the cosmic shear in the last 15 years. The cosmic shear effect has been measured for the first time in 2000. This effect is a distortion

  • I l y a 13,8 milliards d’années naît l’Univers, sous la forme d’une singularité évoluant instantanément en un brouillard chaud, opaque, fait de noyaux d’hydrogène et d’électrons. Pendant plus de 300000 ans, ce plasma s’étend, par inflation•, mais les grains de lumière émis, les photons, sont aussitôt réabsorbés par les particules de matière. L’Univers est

  • Deux Monstres Cosmiques Annihilés, un traitement numérique a <<nettoyé>> les images du fond cosmique d’artifacts inexplicables.

  • An international collaboration of astrophysicists, led by Martin Kilbinger from the Astrophysics Division – AIM Laboratory AIM at CEA Saclay-Irfu and the Institute of Astrophysics Paris, has obtained the largest survey of galaxy images that are deformed by gravitation. More than 4.2 million galaxies have been observed during more than 500 nights at the Canada-France Hawaii Telescope (CFHT) with the camera MegaCam, built
