The correlation of the Lyman-alpha forest and metals in close pairs of hight-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We derive the transverse flux correlation function in the Lyman-alpha forest at z~2.1 from VLT-FORS observations of a total of 32 pairs of quasars. The shape and correlation length…
STEllar Content and Kinematics from high resolution galactic spectra via Maximum A Posteriori
P. Ocvirk, C. Pichon, A. Lancon +1
We introduce STECKMAP (STEllar Content and Kinematics via Maximum A Posteriori), a method to recover the kinematical properties of a galaxy simultaneously with its stellar content…
Stellar Content from high resolution galactic spectra via Maximum A Posteriori
P. Ocvirk, C. Pichon, A. Lancon +1
This paper describes STECMAP (STEllar Content via Maximum A Posteriori), a flexible, non-parametric inversion method for the interpretation of the integrated light spectra of galax…
The Sources of Intergalactic Metals
E. Scannapieco, C. Pichon, B. Aracil +5
We study the clustering properties of metals in the intergalactic medium (IGM) as traced by 619 CIV, 81 SiIV, N >= 10^12 cm^-2 and 316 MgII, and 82 FeII N >= 10^11.5 cm^-2 absorpti…
Modelling and interpreting optical spectra of galaxies at R=10000
Ariane Lancon, Pierre Ocvirk, Damien Le Borgne +5
One way to extract more information from the integrated light of galaxies is to improve the spectral resolution at which observations and analysis are carried out. The population s…
