Strong-lensing analysis of MS 1358.4+6245: New multiple images and implications for the well-resolved z= 4.92 galaxy
A Zitrin, T Broadhurst, D Coe… - Monthly Notices of …, 2011 - academic.oup.com
We present a strong-lensing analysis of the galaxy cluster MS 1358.4+ 6245 (z= 0.33), in
deep six-band HST/ACS imaging. In addition to the well-studied system at z= 4.92, our …

Meso-structure in three strong-lensing systems
P Saha, LLR Williams, I Ferreras - The Astrophysical Journal, 2007 - iopscience.iop.org
We map substructure in three strong-lensing systems having particularly good image data:
the galaxy lens MG J0414+ 053 and the clusters SDSS J1004+ 411 and ACO 1689. Our …
