(The American Astronomical Society, 2013)We measure the two-point cross-correlation function of C iv absorber systems and quasars, using spectroscopic data from the Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey (BOSS; Data Release 9). ...

(2016)We statistically study the physical properties of a sample of narrow absorption line (NAL) systems looking for empirical evidences to distinguish between intrinsic and intervening NALs without taking into account any a ...

(2006)We study the three-dimensional distribution of non-virialized matter at z ∼ 2 using highresolution spectra of quasi-stellar object (QSO) pairs and simulated spectra drawn from cosmological hydrodynamical simulations.We ...
