The time delay of the quadruple quasar RX J0911.4+0551
Jens Hjorth, Ingunn Burud, Andreas O. Jaunsen +9
We present optical lightcurves of the gravitationally lensed components A (=A1+A2+A3) and B of the quadruple quasar RX J0911.4+0551 (z = 2.80). The observations were primarily obta…

An optical time-delay estimate for the double gravitational lens system B1600+434
I. Burud, J. Hjorth, A. O. Jaunsen +7
We present optical I-band light curves of the gravitationally lensed double QSO B1600+434 from observations obtained at the Nordic Optical Telescope (NOT) between April 1998 and No…

High resolution optical and near-IR imaging of the quadruple quasar RX J0911.4+0551
I. Burud, F. Courbin, C. Lidman +10
We report the detection of four images in the recently discovered lensed QSO RX J0911.4+0551. With a maximum angular separation of 3.1", it is the quadruply imaged QSO with the wid…
