Strong-lensing optical depths in a ΛCDM universe – II. The influence of the stellar mass in galaxies
Strong-lensing optical depths in a ΛCDM universe – II. The influence of the stellar mass in galaxies
We investigate how strong gravitational lensing in the concordance LCDM cosmology is affected by the stellar mass in galaxies. We extend our previous studies, based on ray-tracing through the Millennium Simulation, by including the stellar components predicted by galaxy formation models. We find that the inclusion of these components greatly …
