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…
Keck Spectroscopy of Faint 3 < z < 7 Lyman Break Galaxies: III. The Mean Ultraviolet Spectrum at z=4
Tucker Jones, Daniel P. Stark, Richard S. Ellis
We present and discuss the mean rest-frame ultraviolet spectrum for a sample of 81 Lyman Break Galaxies (LBGs) selected to be B-band dropouts with a mean redshift of z=3.9 and appa…
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…
Assessing the redshift evolution of massive black holes and their hosts
Marta Volonteri, Daniel P. Stark
Motivated by recent observational results that focus on high redshift black holes, we explore the effect of scatter and observational biases on the ability to recover the intrinsic…
Keck Spectroscopy of Faint 3<z<8 Lyman Break Galaxies:- Evidence for a Declining Fraction of Emission Line Sources In the Redshift Range 6<z<8
M. A. Schenker, D. P Stark, R. S. Ellis +5
Using deep Keck spectroscopy of Lyman break galaxies selected from infrared imaging data taken with WFC3/IR onboard the Hubble Space Telescope, we present new evidence for a revers…
A critical analysis of the UV-continuum slopes of high-redshift galaxies; no evidence (yet) for extreme stellar populations at z > 6
J. S. Dunlop, R. J. McLure, B. E. Robertson +4
It has recently been reported that the faintest galaxies at z~6-7 display extremely blue UV continuum slopes, with a UV power-law index beta ~ -3. Such slopes are bluer than previo…
