Spitzer and Hubble Constraints on the Physical Properties of the z~7 Galaxy Strongly Lensed by Abell 2218
E. Egami, J. -P. Kneib, G. H. Rieke +10
We report the detection of a z~7 galaxy strongly lensed by the massive galaxy cluster Abell 2218 (z=0.175) at 3.6 and 4.5 um using the Spitzer Observatory and at 1.1 um using the H…
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…
Very High-Redshift Lensed Galaxies
R. Pello, D. Schaerer, J. Richard +2
We review in this paper the main results recently obtained on the identification and study of very high-z galaxies usinglensing clusters as natural gravitational telescopes. We pre…
Detection of CO from SMM J16359+6612, The Multiply Imaged Submillimeter Galaxy Behind A2218
Kartik Sheth, Andrew W. Blain, Jean-Paul Kneib +3
We report the detection of CO (=32) line emission from all three multiple images (A,B and C) of the intrinsically faint ( 0.8 mJy) submillimeter-selected galaxy SMM…
Molecular Gas in a z~2.5 Triply-Imaged, sub-mJy Submillimetre Galaxy Typical of the Cosmic Far-Infrared Background
Jean-Paul Kneib, Roberto Neri, Ian Smail +4
We present the results of observations from the IRAM array of the submm galaxy SMMJ16359+6612 lying at z=2.516 behind the massive cluster A2218. The foreground gravitational lens p…
A CFH12k lensing survey of X-ray luminous galaxy clusters - I: Weak lensing methodology
S. Bardeau, J. -P. Kneib, O. Czoske +4
We present the weak lensing methodology applied to our multi-colour imaging survey of X-ray luminous galaxy clusters conducted with the wide field CFH12k camera. This method, which…
