S09
Étudier l’évolution des galaxies et la cosmologie dans la perspective des futurs grands observatoires.
Contact : atcg@services.cnrs.fr
Les relevés spectroscopiques massifs transformeront des pans entiers de l’astronomie, allant de l’archéologie galactique à la mesure des paramètres cosmologiques et en passant par l’étude de la nature de l’énergie noire. De même, le SKA ouvrira la voie à l’étude de la réionisation et à sa tomographie, et fournira une vue inédite et fondamentale du gaz HI dans les galaxies depuis l’Univers local jusqu’au midi cosmique (z~2). L’ELT, quant à lui, nous permettra de disséquer l’émission des galaxies les plus lointaines, d’étudier en détail la dynamique galactique au-delà de l’Univers local et les populations stellaires des galaxies proches.
Le futur n’ayant jamais été si proche, le besoin de structuration et de préparation de notre communauté est aujourd’hui criant alors même qu’il existe de nombreuses opportunités de synergies méthodologiques et scientifiques. C’est dans ce contexte que nous organisons un atelier autour des quatre axes de l’ATCG (modèle d’Univers, formation et évolution des grandes structures, formation et évolution des galaxies, galaxies proches : archéologie et matière noire galactique) réunissant ainsi des équipes travaillant sur des sujets scientifiques variés mais liés aux interfaces et, surtout, partageant des outils et des méthodologies qui pourraient (et devraient) être mis en commun.
