Bayesian analysis of joint strong gravitational lensing and dynamic galactic mass in SLACS: evidence of line-of-sight contamination
Antonio C. C. Guimarães, Laerte Sodré
We readdress the calculation of the mass of early-type galaxies using strong gravitational lensing and stellar dynamics. Our sample comprises 27 galaxies in the Sloan Lens ACS (SLA…

Cosmic Evolution Impressions on Lensing Maps
Antonio C. C. Guimarães
I investigate through simulations the redshift dependence of several lensing measures for two cosmological models, a flat universe with a cosmological constant (\LambdaCDM), and an…

Studying the LSS through weak gravitational lensing maps
Antonio C. C. Guimarães
Weak gravitational lensing is a promising tool for the study of the mass distribution in the Universe. Here we report some partial results that show how lensing maps can be used to…
