The CosmoStat laboratory is an interdisciplinary research group at CEA Saclay, near Paris/France. It is part of the astrophysics division (SAp - Service d'Astrophysique / SEDI - Service Electronique Détecteurs et Informatique) at the Institute of Research into the Fundamental Laws of the Universe (IRFU). CosmoStat is also part of AIM (Astrophysics, Instrumentation and Modelling), a mixed research unit of CEA, CNRS, and Université Paris-Diderot (Paris 7). We are part of the newly created Université Paris-Saclay.

The scientific focus of CosmoStat is computational cosmology. The motivation to bring together cosmologists and computer scientists is to develop and apply new methods from statistics, signal processing, and compressed sensing to cosmology and other fields. The main CosmoStat research areas are:

Further, members of CosmoStat are involved in teaching and education:

  • Teaching: Teach students and young researchers how to analyze astronomical data.
  • Dissemination: Take opportunity to disseminate our idea and tools in and outside the astronomical field (CEA, CNRS, University, Industry...).

Featured results

  • THE CLEANEST CMB MAP: First joint reconstruction from WMAP9 and Planck PR1 data with LGMCA
