Microlensing results from APO monitoring of the double quasar Q0957+561A,B between 1995 and 1998
Joachim Wambsganss, Robert W. Schmidt, Wesley N. Colley +2
If the halo of the lensing galaxy 0957+561 is made of massive compact objects (MACHOs), they must affect the lightcurves of the quasar images Q0957+561 A and B differently. We sear…

Limits on MACHOs from microlensing in the double quasar Q0957+561
Robert Schmidt, Joachim Wambsganss
The light curves of the two images of the double quasar Q0957+561 as obtained by Kundic et al. (1997) are almost identical, except for an overall time delay and scaling factor. Thi…
