Abstract
The EROS 2 microlensing experiment has completed the analysis of three years of Galactic disk data, and two years of SMC and LMC data. The Galactic disk data is in agreement with models including a bar. The SMC and LMC data strongly limit the amount of compact objects in the Galactic halo. Combining the results from EROS 2 and EROS 1 excludes in particular (at 95 % C. L.) that more than 10 % of the halo be made of objects with a mass between 10−6 M ⊙ and 10−6 M ⊙, and more than 40 % of objects with a mass between 10−7 M ⊙ and 1M ⊙. Analysis of the spatial distribution of LMC events, and comparison of LMC and SMC events in the near future should help discriminate between halo microlensing and other backgrounds like Magellanic Cloud self-lensing and unexpected variable stars.
