Strong and weak lensing analysis of cluster Abell 2219 based on optical and near infrared data
J. Bezecourt, H. Hoekstra, M. E. Gray +3
We present a gravitational lensing study of the massive galaxy cluster A2219 (redshift 0.22). This investigation is based on multicolour images from U through H, which allows photo…

Cluster Reconstruction from Combined Strong and Weak Lensing
Prasenjit Saha, Liliya L. R. Williams, Hanadi AbdelSalam
The lensing information provided by multiple images, arclets, and statistical distortions can all be formulated as linear constraints on the arrival-time surface, and hence on the…

Cluster Mass Profile from Lensing
Hanadi M. AbdelSalam, Prasenjit Saha, Liliya L. R. Williams
We propose a new technique to reconstruct non-parametrically the projected mass distribution of galaxy clusters from their gravitational lens effect on background galaxies. The bea…
