C iv absorption in damped and sub - damped Lyman - α systems Correlations with metallicity and implications for galactic winds at z ≈ 2 − 3 ⋆
We present a study of C iv absorption in a sample of 63 damped Lyman-α (DLA) systems and 11 sub-DLAs in the redshift range 1.75<zabs<3.61, using a dataset of high-resolution (6.6 kms −1 FWHM), high signal-to-noise VLT/UVES spectra. Narrow and broad C iv absorption line components indicate the presence of both warm, photoionized and hot, collisionally ionized gas. We report new correlations betw...
متن کاملMetallicity Evolution of Damped Lyman-α Systems
According to Pei, Fall & Hauser (1999), the global metallicity evolution of the Universe can be represented by the ratio of the total metal content to the total gas content measured in Damped Lyman–α (DLA) systems (the “column density weighted metallicity” à la Pettini). To minimize dust obscuration effects, a DLA sample with negligible dust content is considered, namely, 50 DLAs with logNHI < ...
متن کاملChemical evolution and depletion pattern in Damped Lyman α systems
Dust depletion plays a key role in understanding the nature of Damped Lyman α systems(DLAs). In this paper we point out a previously unnoticed anticor-relation between the observed abundance ratio [X/Zn] (where Zn is assumed to be undepleted and X stands for the refractories Fe, Cr and Ni) and metal column density ([Zn/H]+log(N HI)) in DLAs. We suggest that this trend is an unambiguous sign of ...
متن کاملA Metallicity-spin Temperature Relation in Damped Lyman-α Systems
We report evidence for an anti-correlation between spin temperature Ts and metallicity [Z/H], detected at 3.6σ significance in a sample of 26 damped Lyman-α absorbers (DLAs) at redshifts 0.09 < z < 3.45. The anti-correlation is detected at 3σ significance in a sub-sample of 20 DLAs with measured covering factors, implying that it does not stem from low covering factors. We obtain Ts = (−0.68±0....
متن کاملDamped Lyman-α systems in high-resolution hydrodynamical simulations
We investigate the properties of Damped Lyman-α systems (DLAs) using high-resolution and large box-size cosmological hydrodynamical simulations of a ΛCDM model. The numerical code used is a modification of GADGET-2 with a self consistent implementation of the metal enrichment mechanism (Tornatore et al. 2007). We explore the numerical convergence of some relevant physical quantities and we vary...
