Measuring the Interstellar Medium Content of Nearby, Luminous, Type 1 and Type 2 QSOs through CO and [C ii]

The Astrophysical Journal
We present observations of CO(1–0) and CO(2–1) lines from the Institut de radioastronomie millimétrique 30 m telescope toward 20 nearby, optically luminous type 2 quasars (QSO2s) and observations of the [C ii ] 158 μ m line from the Stratospheric ...

Orientation Effects in QSO Spectra

The Astrophysical Journal, 1993
The consequences of anisotropic continuum emission for the equivalent-width distribution of QSOs are investigated and compared with observations from a large QSO survey. Isotropic line emission is assumed, and a variety of continuum anisotropy models are investigated. Far fewer high equivalent width QSOs are observed than most models predict.

Quasars Clustering at z approx 3 on Scales less sim 10 h^{-1} Mpc

, 2003
We test the hypothesis whether high redshift QSOs would preferentially appear in small groups or pairs, and if they are associated with massive, young clusters.

Polarization of Quasars: Electron Scattering in the Broad Absorption Line Region

, 2005
It is widely accepted that the broad absorption 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 ...
