Mapping cosmic matter distribution  in radio, through the observation of 21 cm radiation of neutral atomic hydrogen is a complementary method to optical surveys to study Large Scale Structures (LSS) and more specifically, the Baryon Acoustic Oscillations (BAO). An R&D … Continue reading →

La cartographie de l’univers en radio, à travers l’observation de la raie à 21 cm de l’hydrogène atomique, constitue une approche complémentaire aux relevés optiques pour l’étude des grandes structures, et des oscillations acoustiques baryoniques (BAO) en particulier. Un programme de … Continue reading →
