Exploring the gravitationally lensed system HE1104-1805: VLT spectroscopy of the lens at z=0.729

C. Lidman, F. Courbin, J. -P. Kneib +3

Using FORS2, mounted on Kueyen (UT2 of the VLT), we have obtained the redshift of the lensing galaxy in the gravitational lens system HE1104-1805. We measure z=0.729, in good agree…
