Description
Gravitational lensing has become an important tool to study the mass distribution in structures and to detect faint and high-redshift galaxies. Predictions usually assume a fix and smooth mass distribution for the galaxies and galaxy clusters that serve as lenses. By combining the results of the dark matter distribution from the Millennium simulation together with the predictions of galaxy properties from semi-analytic models, we have computed the effect of gravitational lensing in lightcone simulations. In this talk I will describe two approaches of our work: at low-redshift, the comparison of our model results with the SDSS SLACS lens survey galaxies, and at high-redshift, the flux magnification of dust-obscured galaxies and its effects in their number counts for Herschel and SCUBA-2.
