Abstract:
We investigate the relative distribution of the gaseous contents of
the Universe (as traced by a sample of Lyα absorbers), and the
luminous baryonic matter (as traced by a redshift survey of galaxies
in the same volume searched for Lyα absorbers), along 16 lines
of sight (LOS) between redshifts 0 and 1. Our galaxy redshift survey
was made with the multi-object spectrograph on the
Canada-France-Hawaii Telescope and, when combined with galaxies from
the literature in the same LOS, gives us a galaxy sample of 636
objects. By combining this with an absorption-line sample of 406
absorbing systems drawn from published works, we are able to study the
relationship between gas and galaxies over the latter half of the age
of the Universe.
