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…
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…
Spectroscopic analysis of newborn massive stars in SMC N81
F. Martins, D. Schaerer, M. Heydari-Malayeri
We present the first results of a spectroscopic study of young massive stars in the SMC High Excitation Blob N81. These stars have Mv values which are ~ 2 mag smaller than those of…
The nuclear processes responsible for the CNO synthesis
M. Arnould, L. Siess, S. Goriely
The abundances of the isotopes of the elements C, N and O are mainly affected by the cold CNO cycles in non-explosive stellar situations, or by the hot CNO chains that can develop…
