Where is the matter in the Merging Cluster Abell 2218?
Árdís Elíasdóttir, Marceau Limousin, Johan Richard +6
We present a parametric strong lensing model of the cluster Abell 2218 based on HST ACS data. We constrain the lens model using 8 previously known multiply imaged systems, of which…
The strong transformation of spiral galaxies infalling into massive clusters at z~0.2
L. Cortese, D. Marcillac, J. Richard +8
We describe two peculiar galaxies falling into the massive galaxy clusters Abell 1689 (z~0.18) and 2667 (z~0.23) respectively. Hubble Space Telescope images show extraordinary trai…
Response to "Reanalysis of the spectrum of the z=10 galaxy ISAAC/VLT observations of a lensed galaxy at z=10.0" by Weatherley et al. (astro-ph/0407150)
R. Pello, J. Richard, J. -F. Le Borgne +1
In a recent posting of a submitted paper Weatherley et al. re-analyse the spectroscopic data from our observations of Abell 1835 IR 1916, a galaxy we claimed to be at redshift z=10…
Observing z>7 sources with the GTC
R. Pello, D. Schaerer, J. Richard +2
We present the first results obtained from our pilot ultra-deep near-IR survey with ISAAC/VLT, aimed at the detection of z>7 sources using lensing clusters as natural Gravitational…
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…
