Searching for the first galaxies through gravitational lenses
D. Schaerer, R. Pello, J. Richard +7
Observing the first galaxies formed during the reionisation epoch, i.e. approximately within the first billion years after the Big Bang, remains one of the challenges of contempora…
3D Lyman-alpha radiation transfer. I. Understanding Lyman-alpha line profile morphologies
Anne Verhamme, Daniel Schaerer, Antonella Maselli
Using a Monte Carlo technique, we have developed a 3D lyman-alpha radiation transfer code allowing for prescribed arbitrary hydrogen density, ionisation, temperature structures, an…
Constraining the population of 6 < z < 10 star-forming galaxies with deep near-IR images of lensing clusters
Johan Richard, Roser Pello, Daniel Schaerer +2
(abridged) We present the first results of our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z~6-10. Deep near-IR photometry of tw…
High spatial resolution mid-infrared spectroscopy of the starburst galaxies NGC 3256, IIZw40 and Henize 2-10
N. L. Martin-Hernandez, D. Schaerer, E. Peeters +2
In order to show the importance of high spatial resolution observations of extra-galactic sources when compared to observations obtained with larger apertures such as ISO, we prese…
Detection of Wolf-Rayet stars in host galaxies of Gamma-Ray Bursts (GRBs): are GRBs produced by runaway massive stars ejected from high stellar density regions ?
F. Hammer, H. Flores, D. Schaerer +3
We have obtained deep spectroscopic observations of several nearby gamma-ray burst (GRB) host galaxies revealing for the first time the presence of Wolf-Rayet (WR) stars and numero…
