It has also been thought line_3: that quasars may expel gas into the intergalactic medium, leading to line_4: large-scale enrichment at an early epoch. In either case, one may expect to line_5: find gas within the parent galaxies of quasars, and large gaseous halos around line_6: them. Other possibilities have been suggested - protogalactic disks, line_7: protoclusters, residual pancake structures - the remains of which might also line_8: appear as halos around quasars. Narrow-band observations of quasars with the line_9: ST will not only address these fundamental issues, but will at the same time line_10: touch on several others, including the nature of the parent galaxy, its line_11: evolution with redshift, the presence of nearby galaxies and possible line_12: protogalaxies, and the nature of the objects causing quasar absorption lines. ! ! end of abstract general_form_proposers: lname: PERRYMAN fname: M.
