Starbursts at z >~6: from the present to Herschel and ALMA
Daniel Schaerer, Roser Pello
The SED of the lensed z=6.56 galaxy HCM6A behind the cluster Abell 370 has been analysed. We find clear indications for the presence of dust in this galaxy, and we estimate the pro…
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…
Expected properties of primeval galaxies and confrontation with existing observations
Daniel Schaerer
We discuss the expected spectral properties of starbursts of zero and very low metallicity covering their restframe EUV and UV to optical spectra. The main criteria to establish su…
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…
