Radio line and continuum observations of quasar-galaxy pairs and the origin of low reshift quasar absorption line systems

open access: yes, 1990
There are a number of known quasars for which our line of sight to the high redshift quasar passes within a few Holmberg radii of a low redshift galaxy.

A quasar without broad Lyα emission

open access: yes, 2004
The z = 3.02 quasar SDSS J095253.83+011421.9 exhibits broad metal-line emission ( C IV FWHM similar or equal to 9000 km s(-1)), but broad Lyalpha emission is not present.

A synoptic survey of narrow quasar absorption lines from the Sloan Digital Sky Survey

open access: yes, 2011
Repeat spectroscopic observations from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) provide an unprecedented opportunity to study the properties of thousands of quasar absorption lines (QALs) in the time domain.
