Detection of the galaxy lensing the doubly imaged quasar SBS 1520+530.

CRAMPTON D., SCHECHTER P.L. and BEUZIT J.-L.

Abstract (from CDS):

H-band observations with a spatial resolution of 0".15 carried out with the Canada-France-Hawaii Telescope adaptive optics system show a galaxy between the components of the double broad absorption line QSO SBS 1520+530, thereby confirming this system as a gravitational lens. The galaxy is located 0".40 from the fainter of the two QSO images and is offset 0".12 from the line joining them. The H magnitude of the lensing galaxy is ∼1 mag fainter than expected from the velocity dispersion derived for the lensing galaxy were it at z = 0.72 or z = 0.81, the redshifts of the two absorption-line systems.
