Where is the matter in the Merging Cluster Abell 2218?
Árdís Elíasdóttir, Marceau Limousin, Johan Richard +6
We present a parametric strong lensing model of the cluster Abell 2218 based on HST ACS data. We constrain the lens model using 8 previously known multiply imaged systems, of which…
A Bayesian approach to strong lensing modelling of galaxy clusters
Eric Jullo, Jean-Paul Kneib, Marceau Limousin +3
In this paper, we describe a procedure for modelling strong lensing galaxy clusters with parametric methods, and to rank models quantitatively using the Bayesian evidence. We use a…
The strong transformation of spiral galaxies infalling into massive clusters at z~0.2
L. Cortese, D. Marcillac, J. Richard +8
We describe two peculiar galaxies falling into the massive galaxy clusters Abell 1689 (z~0.18) and 2667 (z~0.23) respectively. Hubble Space Telescope images show extraordinary trai…
A Survey for Supernovae in Massive High-Redshift Clusters
Keren Sharon, A. Gal-Yam, D. Maoz +12
We describe our ongoing program designed to measure the SN-Ia rate in a sample of massive z=0.5-0.9 galaxy clusters. The SN-Ia rate is a poorly known observable, especially at high…
ZEN and the search for high-redshift galaxies
J. P. Willis, F. Courbin, J-P. Kneib +1
We present the ZEN (z equals nine) survey: a deep, narrow J-band search for proto-galactic Lya emission at redshifts z=9. In the first phase of the survey, dubbed ZEN1, we combine…
Quantifying Substructure Using Galaxy-Galaxy Lensing in Distant Clusters
Priyamvada Natarajan, Jean-Paul Kneib, Ian Smail +1
We present high-resolution mass reconstructions for five massive cluster-lenses spanning a redshift range from z = 0.18 - 0.57 utilizing archival Hubble Space Telescope data and ap…
