    • Extended Lyα emission around quasars with eclipsing damped Lyα systems 
      Fathivavsari, H.; Petitjean, P.; Noterdaeme, P.; Paris, I.; Finley, H.; López, S.; Srianand, R. (2016)
      We present spectroscopic observations of six high redshift (z(em) > 2) quasars, which have been selected for their Lyman alpha (Ly alpha) emission region being only partially covered by a strong proximate (z(abs) similar ...
    • Near-infrared spectroscopic observations of high redshift C I absorbers 
      Zou, Siwei; Petitjean, Patrick; Noterdaeme, Pasquier; Ledoux, Cédric; Krogager, J. K.; Fathivavsari, H.; Srianand, R.; López, S. (EDP Sciences, 2018)
      We study a sample of 17 $z>1.5$ C~{\sc i} absorbers observed with the ESO-VLT spectrograph X-SHOOTER. We derive metallicities, depletion onto dust, extinction by dust and analyse the absorption from Mg~{\sc ii}, Mg~{\sc ...
