LensPerfect: Gravitational Lens Mass Map Reconstructions Yielding Exact Reproduction of All Multiple Images
Dan Coe,Dan Coe,Dan Coe,E. Fuselier,Narciso Benítez,Tom Broadhurst,Brenda Frye,Holland C. Ford +7 more
TL;DR: In this article, the authors presented a new approach to gravitational lens mass map reconstruction, which perfectly reproduced the positions, fluxes, and shears of all multiple images, and each mass map accurately recovered the underlying mass distribution to a resolution limited by the number of multiple images detected.
Journal ArticleDOI

Jee,Simona Mei,Felipe Menanteau,Veronica Motta,W. Zheng,Mark Clampin,G. Hartig +29 more
TL;DR: In this paper, an extensive spectroscopic survey, carried out with VLT FORS, and from an extensive multiwavelength imaging data set from the HST Advanced Camera for Surveys and ground-based facilities, of the cluster of galaxies RDCS J1252.9-2927 was presented.
Journal ArticleDOI

TL;DR: In this article, the inner mass distribution of the relaxed galaxy cluster Abell 383 in deep 16-band HST/ACS+WFC3 imaging taken as part of the CLASH multi-cycle treasury program was examined.
Journal ArticleDOI
A blind test of photometric redshifts on ground-based data
TL;DR: In this paper, the German Ministry for Education and Science (BMBF) through the DLR under the 50 OR 0106, by the BMBF through DESY under the project 05 AV5PDA/3, and by the Deutsche Forschungsgemeinschaft (DFG) under the projects SCHN342/3-1 and ER327/2-1.

TL;DR: In this paper, a photometric redshift for this event places the progenitor at a most probable redshift of 4.6, with a less probable scenario of z = 1.7.
