Quasars as Probes of Late Reionization and Early Structure Formation
Observations of QSOs at z ∼ 5.7 − 6.4 show the appearance of Gunn-Peterson troughs around z ∼ 6, and a change in the slope of the IGM optical depth τ(z) near z ∼ 5.5. These results are interpreted as a signature of the end of the reionization era, which probably started at considerably higher redshifts. However, there also appears to be a substantial cosmic variance in the transmission of the I...
متن کاملHigh-Redshift Quasars as Probes of Galaxy and Cluster Formation
Quasars at large redshifts provide a powerful probe of structure formation in the early universe. Several arguments suggest that the formation of ellipticals and massive bulges may have involved an early quasar phase. At very large redshifts, such structures are likely to be found at the highest peaks of the density field, and would thus be highly biased tracers: the earliest (massive) galaxy f...
متن کاملBroad absorption line quasars have the same cool dust emission as quasars without BALs
The results of a sub-millimeter survey of SDSS broad C iv absorption line quasars is discussed. It is found that the sub-millimeter flux distribution of BAL quasars is similar to that of non-BAL quasars. This is consistent with the idea that all quasars contain broad absorption line regions, but only a fraction of them are visible along our line-of-sight. The observations are inconsistent with ...
متن کاملPolarization of Quasars: Resonant Line Scattering in the Broad Absorption Line Region
Recent works showed that the absorbing material in broad absorption line (BAL) quasars is optically thick to major resonant absorption lines. This material may contribute significantly to the polarization in the absorption lines. In this paper, we present a detailed study of the resonant line scattering process using Monte-Carlo method to constrain the optical depth, the geometry and the kinema...
متن کاملPolarization of Quasars: Electronic Scattering in the Broad Absorption Line Region
It is widely accepted that the broad absoption line region (BALR) exists in most (if not all) quasars with a small covering factor. Recent works showed that the BALR is optically thick to soft and even medium energy X-rays, with a typical hydrogen column density of a few 10 to > 10 cm. The electronic scattering in the thick absorber might contribute significantly to the observed continuum polar...
