Three QSOs acting as strong gravitational lenses
F. Courbin, C. Faure, S. G. Djorgovski +8
We report the discovery of three new cases of QSOs acting as strong gravitational lenses on background emission line galaxies: SDSS J0827+5224 (zQSO = 0.293, zs = 0.412), SDSS J091…

VLT adaptive optics search for luminous substructures in the lens galaxy towards SDSS J0924+0219
C. Faure, D. Sluse, N. Cantale +4
Anomalous flux ratios between quasar images are suspected to be caused by substructures in lens galaxies. We present new deep and high resolution H and Ks imaging of the strongly l…
