Abstract (from CDS):

We present the analysis of the first two years of a search for microlensing of stars in the Small Magellanic Cloud with the eros (Experience de Recherche d'Objets Sombres) project. A single event is detected, already present in the first year analysis. This low event rate allows us to put new constraints on the fraction of the Galactic Halo mass due to compact objects in the mass range [10^–2, 1]M_☉. These limits, along with the fact that the two smc events observed so far are probably due to smc deflectors, suggest that lmc and smc self-lensing may dominate the event rate.
