Beacons into the Cosmic Dark Ages: Boosted transmission of Ly from UV bright galaxies at
Charlotte A. Mason, Tommaso Treu, Stephane de Barros +6
Recent detections of Lyman alpha (Ly) emission from galaxies were somewhat unexpected given a dearth of previous non-detections in this era when the intergalactic medium…
The Universe is Reionizing at z~7: Bayesian Inference of the IGM Neutral Fraction Using Ly Emission from Galaxies
Charlotte A. Mason, Tommaso Treu, Mark Dijkstra +5
We present a new flexible Bayesian framework for directly inferring the fraction of neutral hydrogen in the intergalactic medium (IGM) during the Epoch of Reionization (EoR, z~6-10…
Emission line properties from broad-band photometry: Impact on selection and physical parameter estimation
S. de Barros, H. Nayyeri, N. Reddy +1
Several works have now shown that nebular emission can have a significant impact on broad-band photometry of high-redshift galaxies (), and how this can affect parameter est…
Properties of Lyman Break Galaxies. II. Impact of nebular emission at high redshift
S. de Barros, D. Schaerer, D. P. Stark
We present a homogeneous, detailed analysis of the spectral energy distribution (SED) of 1700 LBGs from the GOODS-MUSIC catalogue with deep multi-wavelength photometry from…
Properties of z~3-6 Lyman break galaxies. II. Testing star formation histories and the SFR-mass relation with ALMA and near-IR spectroscopy
Daniel Schaerer, Stephane de Barros, Panos Sklias
We examine the dependence of derived physical parameters of distant Lyman break galaxies (LBGs) on the assumed star formation histories (SFHs), their implications on the SFR-mass r…
The importance of nebular emission for SED modeling of distant star-forming galaxies
Daniel Schaerer, Stephane de Barros
We highlight and discuss the importance of accounting for nebular emission in the SEDs of high redshift galaxies, as lines and continuum emission can contribute significantly or su…
LBG properties from z~3 to z~6
Stephane de Barros, Daniel Schaerer, Daniel P. Stark
We analyse the spectral energy distribution (SED) of U, B, V and i-dropout samples from GOODS-MUSIC and we determine their physical properties, such as stellar age and mass, dust a…
On Lya emission in z~3-6 UV-selected galaxies
Daniel Schaerer, Stephane de Barros, Daniel P. Stark
Determining Lya properties of distant galaxies is of great interest for various astrophysical studies. We examine how the strength of Lya emission can be constrained from broad-ban…
On the physical properties of z~6-8 galaxies
Daniel Schaerer, Stephane de Barros
We analyse the spectral energy distributions (SEDs) of the most distant galaxies discovered with the Hubble Space telescope and from the COSMOS survey and determine their physical…
Escape of about five per cent of Lyman-alpha photons from high-redshift star-forming galaxies
Matthew Hayes, Goran Ostlin, Daniel Schaerer +7
The Lyman-alpha (Lya) emission line is the primary observational signature of star-forming galaxies at the highest redshifts, and has enabled the compilation of large samples of ga…
The impact of nebular emission on the ages of z~6 galaxies
Daniel Schaerer, Stephane de Barros
We examine the influence of nebular continuous and line emission in high redshift star forming galaxies on determinations of their age, formation redshift and other properties from…
