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:
- Statistics & Signal Processing: Develop new methods for analyzing astronomical data, and especially in cosmology (PLANCK, Euclid, etc.) where the needs of powerful statistical methods are very important.
- Cosmology: Analyze and interpret data. This includes CMB, weak lensing, and other fields such as galaxy clustering and BAOs.
- Projects: Participation to large astronomical space observatories such as PLANCK, FERMI, HERSCHEL, Euclid, etc.
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...).
