On metal abundances in QSO absorbers
S. A. Levshakov
I review our recent results concerning the metal abundances in quasar absorption-line spectra obtained with the UVES/VLT, HIRES/ KECK, and STIS/HST spectrographs. The analysis is b…

Extremely metal-poor Lyman limit system at z = 2.917 toward the quasar HE 0940-1050
S. A. Levshakov, I. I. Agafonova, M. Centurion +1
We report on detailed Monte Carlo inversion analysis of the Lyman limit system observed at z = 2.917 in the VLT/UVES spectrum of the quasar HE 0940-1050. Metal absorption lines of…
