A hyperluminous galaxy at z = 2.8 found in a deep submillimetre survey
Rob Ivison, Ian Smail, J. -F. Le Borgne +5
We present a detailed study of SMM 02399-0136, a hyperluminous, active galaxy selected from a sub-mm survey of the distant Universe. This galaxy is the brightest source in the fiel…
Gravitational Lensing as a Cosmological Probe
J. -P. Kneib
Gravitational Lensing is an efficient tool to probe: the mass distribution of collapsed systems: galaxies and clusters; high redshift objects thanks to the gravitational amplificat…
The Mass/Light Ratio of Early-Type Galaxies: Constraints from Gravitational Lensing in the Rich Cluster AC114
Priyamvada Natarajan, Jean-Paul Kneib, Ian Smail +1
We present a new wide field image of the distant cluster AC114 () obtained with Wide Field and Planetary Camera II onboard the Hubble Space Telescope. This image considerab…
Modelling the Cloverleaf: Contribution of a Galaxy Cluster at z~1.7
J. -P. Kneib, D. Alloin, Y. Mellier +3
We present a new investigation of the Cloverleaf (z=2.558) based on the combination of archival HST/WFPC2 data, recent IRAM CO(7-6) maps and wide field CFHT/FOCAM images. The deepe…
Spectroscopic Confirmation of Redshifts Predicted by Gravitational Lensing
Tim Ebbels, Richard Ellis, Jean-Paul Kneib +4
We present deep spectroscopic measurements of 18 distant field galaxies identified as gravitationally-lensed arcs in a Hubble Space Telescope image of the cluster Abell 2218. Redsh…
