An archive of optical and near-infrared spectra of strongly lensed quasars and the lensing galaxies. The spectra are resolved to about a few Ångstroms and are flux-calibrated....

A collection of images of lensed quasars from various sources. Included are images from Maidanak Observatory (ivo://org.gavo.dc/maidanak/res/rawframes/siap), Apache Point...

Candidate gravitational arcs in the 37 deg^2 of CFHTLS-Archive-Research Survey (CARS). The data include their post-stamp images, astrometry, photometry (u*,g',r',i'), geometric...

Reduced frames of lensed quasar observations from Maidanak Observatory. See the referenceURL for details on the reduction procedure and calibration data.

Observations of the lensed quasar Q2237+0305 performed between 1995 and 1998.

This collection includes optical monitorings of gravitationally lensed quasars. The frames can be used to make light curves of quasar images and field objects. From quasar light...
