## Welcome to CosmoStat

The CosmoStat laboratory is an interdisciplinary research group based at CEA Saclay, near Paris, France. The group was founded in 2010 with the aim of bringing together a team of cosmologists and computer scientists in order to find new ways to approach problems in the domains of astrophysics, cosmology and signal processing.

Since its inception, CosmoStat has produced a wealth of software and publications, and contributed to the development of several excellent researchers. Members of CosmoStat have also significantly contributed to various big international projects such as Planck, Fermi, Herschel and Euclid.
