Lyman-α absorption: links between CSS quasars and high-redshift radio galaxies
نویسنده
چکیده
Spectroscopy of high-redshift compact steep-spectrum (CSS) quasars shows a high incidence of Ly-α absorption close to the quasar redshift (zabs ≈ zem). Associated absorption systems like these are rare in other types of radio sources, with the notable exception of high-redshift radio galaxies (HZRGs). CSS quasars and HZRGs share many properties; the hypothesis that they are intrinsically similar objects is presented and discussed.

Gamma-ray Bursts versus Quasars: Lyman-α Signatures of Reionization versus Cosmological Infall
Lyman-α absorption is a prominent cosmological tool for probing both galactic halos and the intergalactic medium at high redshift. We consider a variety of sources that can be used as the Lyman-α emitters for this purpose. Among these sources, we argue that quasars are the best probes of the evolution of massive halos, while γ-ray bursts represent the cleanest sources for studying the reionizat...
متن کاملNICMOS Snapshot Survey of Damped Lyman α Quasars
We image 19 quasars with 22 damped Lyman α (DLA) systems using the F160W filter and the Near-Infrared Camera and Multiobject Spectrograph aboard the Hubble Space Telescope, in both direct and coronagraphic modes. We reach 5σ detection limits of ∼H=22 in the majority of our images. We compare our observations to the observed Lyman-break population of high-redshift galaxies, as well as Bruzual & ...

We use deep HST STIS and NICMOS images of three spectroscopically confirmed galaxy counterparts of high-redshift damped Lyα (DLA) absorbers (one of which is a new discovery) to test the hypothesis that high-redshift DLA galaxies are Lyman-break galaxies. If this hypothesis is correct the emission properties of DLA galaxies must lie within the range of emission properties measured for Lyman-brea...
متن کاملB2 0902+34: a Collapsing Protogiant Elliptical Galaxy at Z=3.4
We have used the visible integral-field replicable unit spectrograph prototype (VIRUS-P), a new integral field spectrograph, to study the spatially and spectrally resolved Lyman-α emission line structure in the radio galaxy B2 0902+34 at z = 3.4. We observe a halo of Lyman-α emission with a velocity dispersion of ≈250 km s−1 extending to a radius of 50 kpc. A second feature is revealed in a spa...
متن کاملGalaxies and Intergalactic Matter at Redshift Z ∼ 3: Overview
We present the first results from a survey of the relative spatial distributions of galaxies, intergalactic neutral hydrogen, and intergalactic metals at high redshift. We obtained high-resolution spectra of 8 bright QSOs at 3.1 < z < 4.1 and spectroscopic redshifts for 431 Lyman-break galaxies (LBGs) at slightly lower redshifts. Comparing the locations of galaxies to the absorption lines in th...
