    Short time-scale fluctuations in the difference light curves of QSO 0957+561A,B: microlensing or noise?
    From optical R-band data of the double quasar QSO 0957+561A,B, we made two new difference light curves (with an overlap of about 330d between the time-shifted...

    Six binary brown dwarf candidates identified by microlensing
    Aims. In single-lens microlensing events, the event timescale (t E) is typically the only measurable parameter that constrains the lens mass. Since t E scales...
