Richard, Johan, Smith, Graham, Kneib, Jean-Paul, Ellis, Richard, Sanderson, Alastair, Pei, Liuyi, ...
We present a statistical analysis of a sample of 20 strong lensing clusters drawn from the Local Cluster Substructure Survey (LoCuSS), based on high resolution Hubble Space Telescope imaging of the...
Smith, Graham P., Ebeling, Harald, Limousin, Marceau, Kneib, Jean-Paul, Swinbank, A. M., Ma, Cheng-Jiun, ...
We present Advanced Camera for Surveys observations of MACSJ1149.5+2223, an X-ray luminous galaxy cluster at z=0.544 discovered by the Massive Cluster Survey. The data reveal at least seven...
Abell 370 revisited: refurbished Hubble imaging of the first strong lensing cluster (2009)
Richard, Johan, Kneib, Jean-Pau, Limousin, Marceau, Edge, Alastair, Jullo, Eric
We present a strong lensing analysis of the galaxy cluster Abell 370 (z=0.375) based on the recent multicolor ACS images obtained as part of the Early Release Observation (ERO) that followed the...
Limousin, Marceau, Jullo, Eric, Richard, Johan, Cabanac, Remi, Kneib, Jean-Paul, Gavazzi, Raphael, ...
A precise modelling of a strong lensing system can be affected by some external mass distribution. In this article, we propose to turn this bother to our advantage and to use precise strong lensing...
Strong gravitational lensing probes of the particle nature of dark matter (2009)
Moustakas, Leonidas A., Abazajian, Kevork, Benson, Andrew, Bolton, Adam S., Bullock, James S., Chen, Jacqueline, ...
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these candidates may have...
Multi-scale cluster lens mass mapping I. Strong Lensing modelling (2009)
We propose a novel technique to refine the modelling of galaxy clusters mass distribution using gravitational lensing. The idea is to combine the strengths of both "parametric" and "non-parametric"...
Richard, Johan, Pei, Liuyi, Limousin, Marceau, Jullo, Eric, Kneib, Jean-Paul
Strong gravitational lensing is a unique tool to model with great accuracy the inner mass distribution of massive galaxy clusters. In particular, clusters with large Einstein radii provide a wealth...
A Bayesian approach to strong lensing modelling of galaxy clusters (2007)
Jullo, Eric, Kneib, Jean-Paul, Limousin, Marceau, Elíasdóttir, Árdis, Marshall, Phil, Verdugo, Tomas
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 publicly available...
Telescope search for decaying relic axions (2007)
Grin, Daniel, Covone, Giovanni, Kneib, Jean-Paul, Kamionkowski, Marc, Blain, Andrew, Jullo, Eric
A search for optical line emission from the two-photon decay of relic axions was conducted in the galaxy clusters Abell 2667 and 2390, using spectra from the VIMOS (Visible MultiObject Spectrograph)...
A statistical study of multiply-imaged systems in the lensing cluster Abell 68 (2007)
Richard, Johan, Kneib, Jean-Paul, Jullo, Eric, Covone, Giovanni, Limousin, Marceau, Ellis, Richard, ...
We have carried out an extensive spectroscopic survey with the Keck and VLT telescopes, targeting lensed galaxies in the background of the massive cluster Abell 68. Spectroscopic measurements are...
