Abstract
A review of the searches for microlensing undertaken by the EROS experiment towards the large (LMC) and the small (SMC) Magellanic clouds is presented in this paper. Although about 75 million star-years have been analyzed by EROS2 towards the LMC, and 25 million star-years towards the SMC, 8 new candidates only have been discovered. The discrepancy between the average event durations observed towards each cloud hints to a different population causing the microlensing events in each case. The low number of events is best presented as an exclusion limit on the halo mass fraction composed of dark objects. These results, combined with those from the previous phase of the EROS experiment, now exclude the entire range from 10 -7 to 20 M ⊙) from a significant contribution to a dark standard isothermal and isotropic halo.
