|Summary / Zusammenfassung||Microlensing and initial mass function of the Galactic bulge
The paper addressing the problem of the shape of the initial mass function of the Galactic bulge using the microlensing observations towards the Galactic center by the MACHO, EROS and OGLE collaborations has appeared. In particular, we considered the duration distribution of the microlensing events. Assuming a power law for the initial mass function we studied the slope, as given by the power law index, both in the brown dwarf and in the main sequence ranges. Moreover, we compared the observed and theoretical, based on Bulge modeling, optical depth proles, which turn out to be in quite good agreement.
