HE 0141 – 3932 : a bright QSO with an unusual emission line spectrum and associated absorption ⋆
HE 0141–3932 (zem = 1.80) is a bright blue radio-quite quasar with an unusually weak Lyα emission line. Large redshift differences (∆z = 0.05) are observed between high ionization and low ionization emission lines. Absorption systems identified at z abs = 1.78, 1.71, and 1.68 show mild oversolar metallicities (Z ≈ 1 − 2Z⊙) and can be attributed to the associated gas clouds ejected from the circ...
متن کاملMolecular QSO Absorption Line Systems
We review observations of molecular absorption line systems at high redshift toward red quasars and gravitational lenses. The steeply falling power law column density distribution function of QSO absorption line systems implies that for every 1000 Ly α forest lines from absorbers with hydrogen column density, NH < 10 15 cm there will be only one system with NH ≥ 10 cm (Hu et al. 1995). Although...
متن کاملAbsorption and emission spectrum
It is well known that main group metal ions with an s* electron configuration form a large variety of polynuclear coordination compounds [l]. Recently it has been suggested that in these compounds a weak metal-metal bonding may exist which is achieved by sp orbital mixing [2]. In particular, calculations on Tl+ clusters were used to support this idea. Unfortunately, the metal-metal interaction ...
متن کاملAbundance Histories for Qso Absorption Line Systems
Abundance histories for QSO absorption line systems as a function of redshift are presented for all metals lighter than gallium. Coupling various conventional cosmological models with a simple, rst{order model for the chemical evolution of the QSO absorption line systems allows transformation of the observed abundance trends in the Galaxy to abundance histories for the gas in QSO absorption lin...
متن کاملElemental Abundances from Intrinsic QSO Emission and Absorption Lines
Several studies have shown that the column densities inferred from broad absorption lines (BALs) require extremely high metallicities and phosphorus overabundances – apparently in conflict with other abundance diagnostics. Here I use HST spectroscopy of the BALQSO PG 1254+047 to argue that the BALs abundance estimates are incorrect, because partial line-of-sight coverage of the continuum source...
