Abstract
We present results of a spectroscopic survey of galaxies around quasars of the HST Key Program. Our sample of Lyα-absorber/galaxy associations, combined with those of published studies, is used to constrain the link between galaxies and Lyα absorbers. There is no strong correlation between the equivalent width of the Lyα absorption and the impact parameter of the galaxy, and the distribution of the velocity difference between the absorber and the galaxy is narrow, FWHM= 240 km s−1. These arguments are compatible with most of the Lyα absorbers tracing the dark matter structures.
