Metal enrichment of the intergalactic medium at z=3 by galactic winds
Studies of quasar absorption lines reveal that the low density intergalactic medium at z ∼ 3 is enriched to 10−10 solar metallicity. This enrichment may have occurred in an early generation of Population III stars at redshift z ∼> 10, by protogalaxies at 6 ∼< z ∼< 10, or by larger galaxies at 3 ∼< z ∼< 6. This paper addresses the third possiblity by calculating the enrichment of the IGM at z ∼>...
متن کاملMetal-enriched, sub-kiloparsec gas clumps in the circumgalactic medium of a faint z = 2.5 galaxy
We report the serendipitous detection of a 0.2 L∗, Lyα emitting galaxy at redshift 2.5 at an impact parameter of 50 kpc from a bright background QSO sightline. A high-resolution spectrum of the QSO reveals a partial Lyman-limit absorption system (NHI = 1016.94±0.10 cm−2) with many associated metal absorption lines at the same redshift as the foreground galaxy. Using photoionization models that ...
متن کاملPolarization of the Lyα Halos Around Sources Before Cosmological Reionization
In Loeb & Rybicki (1999; paper I) it was shown that before reionization, the scattering of Lyα photons from a cosmological source might lead to a fairly compact (∼ 15) Lyα halo around the source. Observations of such halos could constrain the properties of the neutral intergalactic medium (IGM), and in particular yield the cosmological density parameters of baryons and matter on scales where th...
متن کاملThe warm - hot intergalactic medium at z ∼ 2 . 2 : Metal enrichment and ionization source ⋆
Results are presented for our search for warm-hot gas towards the quasar Q 0329−385. We identify ten Ovi systems of which two are within 5000 km s of zem and a third one should be of intrinsic origin. The seven remaining systems have H i column densities 10≤N(H i)≤10 cm. At least ∼1/3 of the individual Ovi sub-systems have temperatures T<1×10 K and cannot originate in collisionally ionized gas....
متن کاملGalaxies at Z = 3 around Dlas 3
RESUMEN El resumen será traducido al español por los editores. We are exploring the connection between damped Ly-alpha absorbers (DLAs) s and Lyman break galaxies (LBGs) using deep – m lim,I (5σ)=26 m AB – broad band imaging (UBVI) of four wide fields (0.25deg 2 each) obtained at the Kitt Peak 4-m telescope with MOSAIC. Each field contains a DLA at z ∼ 3. We want to address the nature of DLAs a...
