Physical Properties of Low-Luminosity Galaxies at z ~ 2
M. Lemoine-Busserolle, T. Contini, R. Pello +3
We report the results obtained from ISAAC/VLT near-IR spectroscopy of two low-luminosity z ~ 1.9 galaxies located in the core of the lensing cluster AC114. The amplification factor…

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…
