En collaboration avec un coll\u00e8gue de Yale, le professeur Abraham a r\u00e9cemment mis au point un nouveau type de t\u00e9lescope, le Dragonfly Telephoto Array, qui est capable de d\u00e9tecter des structures de tr\u00e8s faible luminosit\u00e9 (des objets tr\u00e8s diffus et tr\u00e8s grands) dans l\u2019Univers. Le Dragonfly a d\u00e9j\u00e0 fait quelques d\u00e9couvertes notables, dont une nouvelle classe de galaxie ultra-diffuse. La nature de l\u2019univers \u00e0 faible luminosit\u00e9 \u00e9tant presque inexplor\u00e9e, ces d\u00e9couvertes ne sont probablement que le d\u00e9but de d\u00e9couvertes plus importantes qui se feront gr\u00e2ce au Dragonfly.<\/p>\n
Au cours des deux prochaines ann\u00e9es, avec sa bourse de recherche Killam\u00a0le professeur Abraham souhaite utiliser son t\u00e9lescope pour explorer la nature de la mati\u00e8re noire dans les galaxies ultra-diffuses et pour entreprendre une \u00e9tude \u00e0 grande \u00e9chelle des objets c\u00e9lestes de faible luminosit\u00e9. Il modifiera \u00e9galement le Dragonfly afin de permettre une recherche de la \u00ab\u00a0toile cosmique\u00a0\u00bb, qu’on croit \u00eatre un r\u00e9seau \u00e0 grande \u00e9chelle fait de filaments de mati\u00e8re noire, qui pourrait relier les galaxies entre elles, et qui serait la plus grande structure coh\u00e9rente de l\u2019Univers.<\/p>\n","protected":false},"excerpt":{"rendered":"
