Journal ArticleDOI
Weak lensing density profiles and mass reconstructions of the galaxy clusters Abell 1351 and Abell 1995
TL;DR: In this article, the overall mass distribution of the galaxy clusters Abell 1351 and Abell 1995 using weak gravitational lensing was studied using a finite-field mass reconstruction algorithm, and verified with aperture mass statistics.

TL;DR: In this paper, a virtual multi-colour survey based on public archive images from the CFHT-Legacy-Survey (CARS) is presented, where the main scientific interests are optical searches for galaxy clusters from low to high redshift and their subsequent study with photometric and weak-gravitational lensing techniques.
