An optical time delay for the double gravitational lens system FBQ 0951+2635
P. Jakobsson, J. Hjorth, I. Burud +3
We present optical R-band light curves of the double gravitationally lensed quasar FBQ 0951+2635 from observations obtained at the Nordic Optical Telescope between March 1999 and J…

Exploring the gravitationally lensed system HE 1104-1805: Near-IR Spectroscopy
F. Courbin, C. Lidman, G. Meylan +2
(Abridged) A new technique for the spatial deconvolution of spectra is applied to near-IR (0.95 - 2.50 micron) NTT/SOFI spectra of the lensed, radio-quiet quasar HE 1104-1805. The…

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…
