The Importance of Binary Gravitational Microlensing Events Through High-Magnification Channel

, 2009
We estimate the detection efficiency of binary gravitational lensing events through the channel of high-magnification events. From this estimation, we find that binaries in the separations ranges of 0.1 < s < 10, 0.2 < s < 5, and 0.3 < s < 3 can be ...
