Damped and sub-damped Lyman-? absorbers in z > 4 QSOs
Rodney Guimaraes, Patrick Petitjean, Reinaldo Ramos De Carvalho +5
We present the results of a survey for damped (DLA, log N(H I) > 20.3) and sub-damped Lyman-? systems (19.5 < log N(H I) < 20.3) at z > 2.55 along the lines-of-sight to 77 quasars…

Evidence for overdensity around z_em > 4 quasars from the proximity effect
Rodney Nascimento Guimaraes, Patrick Petitjean, Emmanuel Beaumont Rollinde +5
We study the density field around z_em > 4 quasars using high quality medium spectral resolution ESI-Keck spectra (R~4300, SNR > 25) of 45 high-redshift quasars selected from a tot…
