The ESO UVES Advanced Data Products Quasar Sample - IV. On the deficiency of Argon in DLA systems
Tayyaba Zafar, Giovanni Vladilo, Celine Peroux +5
In this work, we study argon abundances in the interstellar medium of high-redshift galaxies (2<z(abs)<4.2) detected as Damped Lya absorbers (DLA) in the spectra of background quas…
The ESO UVES Advanced Data Products Quasar Sample - III. Evidence of Bimodality in the [N/alpha] Distribution
Tayyaba Zafar, Miriam Centurion, Celine Peroux +4
We report here a study of nitrogen and -capture element (O, S, and Si) abundances in 18 Damped Ly Absorbers (DLAs) and sub-DLAs drawn from the ESO-UVES Advanced Data Products…
Nitrogen Abundances in Damped Ly-alpha Absorbers
Tayyaba Zafar, Miriam Centurion, Paolo Molaro +3
Nitrogen is thought to have both primary and secondary origins depending on whether the seed carbon and oxygen are produced by the star itself (primary) or already present in the i…
