TIME DELAY BETWEEN IMAGES OF THE LENSED QUASAR UM673

TIME DELAY BETWEEN IMAGES OF THE LENSED QUASAR UM673

We study brightness variations in the double lensed quasar UM673 (Q0142-100) with the aim of measuring the time delay between its two images. Methods.. We analyzed the V, R and I-band light curves of the A and B images of UM673, which cover ten observational seasons from August 2001 to November 2010...
