Quasar Absorption Lines

My main interest is all related to quasars absorption liens. Quasars have been used as background sources to study the gaseous phases of a variety of objects that are located along our sight-lines to quasars and producing absorption lines on spectra of the quasars. Examples of such objects include not only intervening absorbers such as intervening galaxies, the intergalactic medium, clouds in the halo of the Milky Way, and the host galaxies of the quasars themselves, but also intrinsic absorbers that are physically associated to the quasar central engines.
