Descripción
In this talk we first make a review on gravitational lensing and microlensing as an introduction, followed by a discussion on the most recent work of our group. The analysis of the spectral data for a sample of lensed systems leads to the extension of the (controversial) results from the Milky Way/LMC/M31 MACHOs up to a sample of galactic halos at cosmological distances, supporting the hypothesis of the very low or even null content in compact objects in galactic halos in general.
