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…
An ISOCAM survey through gravitationally lensing galaxy clusters. II. The properties of infrared galaxies in the A2218 field
A. Biviano, L. Metcalfe, B. McBreen +10
We observed the cluster Abell 2218 (z=0.175), with ISOCAM on board the Infrared Space Observatory, using two filters with reference wavelengths of 6.7 and 14.3 microns. We detected…
Detecting compact dark matter in galaxy clusters via gravitational microlensing: A2218 & A370
Artem Tuntsov, Geraint Lewis, Rodrigo Ibata +1
After decades of searching, the true nature of dark matter still eludes us. One potential probe of the form of dark matter in galaxy clusters is to search for microlensing variabil…
Properties of Faint Distant Galaxies as seen through Gravitational Telescopes
R. Pello, T. Contini, M. Lemoine-Busserolle +5
This paper reviews the most recent developments related to the use of lensing clusters of galaxies as Gravitational Telescopes in deep Universe studies. We summarize the state of t…
Constraints on (Omega_M0, Omega_Lambda) from strong lensing in AC 114
G. Golse, J. -P. Kneib, G. Soucail
We use a strong lensing inversion in the cluster of galaxies AC 114 to derive constraints on the cosmological parameters Omega_M0 and Omega_Lambda. If it is possible to measure spe…
