Discovery of a new gravitational lens

Abstract

On a trouve que le QSO double, faible 1635+267 A, B est pratiquement au meme deplacement vers le rouge z=1,961±0,003. La difference des deplacements vers le rouge, determinee par une technique de correlation croisee est de (3,2±8,5)×10 −4 , correspondant a une difference de vitesses de (33±86) kms −1 seulement. Cette faible valeur et la similitude des spectres suggerent qu'il s'agit d'un nouveau cas de lentille gravitationnelle. Une raie d'absorption dans le spectre du QSO image le plus brillant pourrait etre la signature de la galaxie lentille. Il s'agit du doublet Mg II λ 2799 vu a z lentille =1,118
