| dc.description | Gravitational weak lensing by large scale structures is view as a tool to probe the bias relation between the mass and the light distributions. It is explained how a particular statistic can be used to deproject the 2D mass distribution observed by weak lensing, in order to probe the bias at a given redshift and a given scale. Dependence with the cosmology is written, and observational issues are pointed out, like the importance of the redshift distribution of the galaxies. A signal to noise analysis shows that the scale dependence of the bias can be measured with a rather modest lensing survey size. | |
