| Revisiting the origin of the high metallicities of sub-damped Lyman-alpha systems (2009) | |||||||||
Abstract | |||||||||
| Sub-damped Lyman-alpha systems (sub-DLAs) have previously been found to exhibit a steeper metallicity evolution than the classical damped Lyman-alpha systems (DLAs), evolving to close to solar metallicity by z~1. From new high-resolution spectra of 17 sub-DLAs we have increased the number of measurements of [Fe/H] at z. Comment: 6 pages, 3 figures, MNRAS, in press | |||||||||
