  • Pérez-Ràfols, Ignasi; Miralda-Escudé, Jordi; Arinyo-i-Prats, Andreu; Font-Ribera, Andreu; Mas Ribas, Lluis (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We measure the cosmological bias factor of damped Ly α absorbers (DLAs) from their crosscorrelation with the Ly α forest absorption, as a function of the DLA metal strength, defined from an average of equivalent widths of ...
  • Mas Ribas, Lluis; Miralda-Escude, Jordi; Perez-Rafols, Ignasi; Arinyo-i-Prats, Andreu; Noterdaeme, Pasquier; Petitjean, Patrick; Schneider, Donald P.; York, Donald G.; Ge, Jian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We study the mean absorption spectrum of the Damped Lyα (DLA) population at z ~ 2.6 by stacking normalized, rest-frame-shifted spectra of ~27,000 DLA systems from the DR12 of the Baryon Oscillation Spectroscopic Survey ...
  • Arinyo-i-Prats, Andreu; Mas Ribas, Lluis; Miralda-Escude, Jordi; Perez-Rafols, Ignasi; Noterdaeme, Pasquier (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The bias factor of damped Ly α (DLAs) systems, derived from the cross-correlation with the Ly α forest in absorption spectra of the Baryon Oscillation Spectroscopic Survey of SDSS-III, has been used to infer the characteristic ...
