Final results from EROS Microlensing search for Massive Compact Halo Objects

Abstract : We present the results of the EROS2 search for the hidden galactic matter of the halo through the gravitational microlensing of stars in the Magellanic clouds. Microlensing was also searched for and found in the Milky-Way plane, where foreground faint stars are expected to lens background stars. A total of 67 million of stars were monitored over a period of about 7 years. Hundreds of microlensing candidates have been found in the galactic plane, but only one was found towards the subsample of bright --well measured-- Magellanic stars. This result implies that massive compact halo objects (machos) in the mass range $10^{-7}M_\odot
