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 survey gives photometric redshifts of objects within 275 deg² (−50◦ < α < 60◦ and −1.◦25 < δ < +1.◦25) centered on the Celestial Equator. Each piece of sky has...

The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies selected to have Iab...

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...
