    Time Delay in QSO 0957+561 From 1984-1999 Optical Data
    Photometric optical data of QSO 0957+561 covering the period 1984-1999 are analyzed to discern between the two values of the time delay (417 and 424 days)...

    Time Delay of QSO 0957+561 and Cosmological Implications
    We obtain the time delay between the arrival time of the A and B images of the QSO 0957+561. The results of applying two different methods (the discrete cross...
