Physical properties of DLA metallicity and neutral hydrogen column density
We investigate some basic properties of Damped Lyman alpha systems based on the Semi-Analytical model of disk galaxy formation theory. We derive the DLA metallicity, column density, number density, gas content and cosmic star formation rate by assuming that disks form at the center of dark halos, and the modelled DLAs are selected by Monte Carlo simulation according to the distributions of halo...
متن کاملMultiwavelength investigation of a near - solar metallicity sub - DLA at z abs = 1 . 3647 towards PKS 0237 - 233 ⋆
We searched for 21-cm absorption associated with the zabs= 1.3647 absorption system toward the gigahertz peaked-spectrum source PKS 0237−233 using the Giant Metrewave Radio Telescope. A high quality UVES spectrum shows that C i and C i are detected at this redshift together with C ii, Mg i, Mg ii, Si ii, Al ii, Fe ii and Mn ii. The complex profiles, spread over ∼ 300 km s, are fitted with 21 Vo...

15 صفحه اولVelocity - metallicity correlation for high - z DLA galaxies : Evidence for a mass - metallicity relation ? ⋆
We used our database of VLT-UVES quasar spectra to build up a sample of 70 Damped Lyman-α (DLA) or strong sub-DLA systems with total neutral hydrogen column densities of log N(H ) > ∼ 20 and redshifts in the range 1.7 < z abs < 4.3. For each of the systems, we measured in an homogeneous manner the metallicities relative to Solar, [X/H] (with X = Zn, or S or Si), and the velocity widths of low-...
