Detection of large scale Ly absorbers at large angles to the radio axis of high-redshift radio galaxies using SOAR
M. Silva, A. Humphrey, P. Lagos +4
We present an investigation of the properties of the extended Ly halo and the large-scale \ion{H}{I} absorbing structures associated with 5 high-redshift radio galaxies at z …
Scaling the smoothness of the IGM
R. N. Guimarães, P. Petitjean, E. Rollinde +3
We use, for the first time, the Detrend Fluctuation Analysis (DFA) to study the correlation properties of the transmitted flux fluctuations, in the Lyman- (Ly) Forest along t…
Metallicities, dust and molecular content of a QSO-Damped Lyman-α system reaching log N (H i) = 22: An analog to GRB-DLAs
R. Guimarães, P. Noterdaeme, P. Petitjean +4
We present the elemental abundance and H2 content measurements of a Damped Lyman-α (DLA) system with an extremely large H i column density, log N(H i) (cm-2) = 22.0+/-0.10, at zabs…
Constraining H0 from Lyman-alpha Forest and Baryon Acoustic Oscillations
V. C. Busti, R. N. Guimarães, J. A. S. Lima
A new method is proposed to measure the Hubble constant H0 through the mean transmitted flux observed from high redshift quasars. A semi-analytical model for the cosmological-indep…
High-ion absorption in the proximate damped Lyman-alpha system toward Q0841+129
Andrew J. Fox, Cédric Ledoux, Patrick Petitjean +2
We present VLT/UVES spectroscopy of the quasar Q0841+129, whose spectrum shows a proximate damped Lyman-alpha (PDLA) absorber at z=2.47621 and a proximate sub-DLA at z=2.50620, bot…
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…
