Transition frequency shifts with fine structure constant variation for Fe II: Breit and core-valence correlation correction
S. G. Porsev, K. V. Koshelev, I. I. Tupitsyn +3
Transition frequencies of Fe II ion are known to be very sensitive to variation of the fine structure constant α. The resonance absorption lines of Fe II from objects at cosmologic…

Extinction and metal column density of HI regions up to redshift z~2
G. Vladilo, M. Centurion, S. A. Levshakov +4
We used the photometric database of the Sloan Digital Sky Survey (SDSS) to estimate the reddening of 13 SDSS quasars selected on the basis of the presence of zinc absorption lines…
