A new analysis of the MEGA M31 microlensing events

Abstract_

We discuss the results of the MEGA microlensing campain towards M31. Our analysis is based on an analytical evaluation of the microlensing rate, taking into account the observational constraints as given by the MEGA Collaboration. In particular, we study the spatial and time duration distributions of the microlensing events. We show that only for extreme models of the M31 luminous components it is possible to reconcile the observed MEGA events with the expected self-lensing contribution.
