11. LBQS 1429-0053: a binary quasar rather than a lensed quasar - Faure, C.; Alloin, D.; Gras, S.; Courbin, F.; Kneib, J. -P.; Hudelot, P.
Very deep ESO/VLT FORS1 and ISAAC images, as well as HST NICMOS2 data areused to infer the nature of the quasar pair LBQS 1429-0053 A and B, either abinary quasar or a doubly-imaged lensed quasar.

12. Quasar Absorption Lines - Bechtold, Jill
In this review, we present an introduction to thefield, starting with the techniques used for interpreting absorption linespectra.

13. Quasar-galaxy associations - Thomas, P. A.; Webster, R. L.; Drinkwater, M. J.
There is controversy about the measurement of statistical associationsbetween bright quasars and faint, presumably foreground galaxies.

14. Time Dilation and Quasar Variability - Hawkins, M. R. S.
The timescale of quasar variability is widely expected to show the effects oftime dilation.

15. Explaining Low Redshift Quasar Evolution - Steed, Adam; Weinberg, David H.
We have developed a flexible framework for constructing physical models ofquasar evolution that can incorporate a wide variety of observationalconstraints, such as multi-wavelength quasar luminosity functions (QLFs),estimated masses and accretion rates of active black holes, space densities ofquasar host galaxies, clustering measurements, and the mass function of blackholes in the local universe.

16. Molecular Gas in Quasar Hosts - Barvainis, Richard
The study of molecular gas in quasar host galaxies addresses a number ofinteresting questions pertaining to the hosts' ISM, to unified schemes relatingquasars and IR galaxies, and to the processes fueling nuclear activity.

17. UV observation of a quasar sample - Faïsse, S.; Milliard, B.
The spectral indexes distribution of a quasar sample is derived from a far-UVsurvey.

18. Quasar Clustering and Spacetime Geometry - Popowski, Piotr A.; Weinberg, David H.; Ryden, Barbara S.; Osmer, Patrick S.
The non-Euclidean geometry of spacetime induces an anisotropy in the apparentcorrelation function of high-redshift quasars.
