A Principal Component Analysis of quasar UV spectra at z~3
I. Pâris, P. Petitjean, E. Rollinde +12
From a Principal Component Analysis (PCA) of 78 z~3 high quality quasar spectra in the SDSS-DR7, we derive the principal components characterizing the QSO continuum over the full w…
The Eighth Data Release of the Sloan Digital Sky Survey: First Data from SDSS-III
III collaboration, Hiroaki Aihara, Carlos Allende Prieto +178
The Sloan Digital Sky Survey (SDSS) started a new phase in August 2008, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements…
The correlation of the Lyman-alpha forest in close pairs and groups of high-redshift quasars: clustering of matter on scales 1-5 Mpc
E. Rollinde, P. Petitjean, C. Pichon +4
We study the clustering of matter in the intergalactic medium from the Lyman-alpha forests seen in the spectra of pairs or groups of z ~ 2 quasars observed with FORS2 and UVES at t…
