The evolution of the Si IV content in the Universe from the epoch of reionization to cosmic noon
V. D'Odorico, K. Finlator, S. Cristiani +9
We investigate the abundance and distribution of metals in the high-redshift intergalactic medium and circum-galactic medium through the analysis of a sample of almost 600 SiIV abs…
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 UVES Large Program for testing fundamental physics - III. Constraints on the fine-structure constant from 3 telescopes
T. M. Evans, M. T. Murphy, J. B. Whitmore +10
Large statistical samples of quasar spectra have previously indicated possible cosmological variations in the fine-structure constant, . A smaller sample of higher signal-to-noi…
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…
Limits on the spatial variations of the electron-to-proton mass ratio in the Galactic plane
S. A. Levshakov, D. Reimers, C. Henkel +4
Aims. To validate the Einstein equivalence principle (local position invariance) by limiting the fractional changes in the electron-to-proton mass ratio, mu = m_e/m_p, measured in…
