A HST Spectroscopic study of QSOs with intermediate redshift damped Lyman-alpha systems
Patrick Boisse, Vincent Le Brun, Jacqueline Bergeron +1
We present HST spectra for a sample of six QSOs with intermediate redshift (z_a < 1) damped Ly-alpha systems. These observations aim at measuring the HI column density and detect m…

The nature of intermediate-redshift damped Ly-alpha absorbers
V. Le Brun, J. Bergeron, P. Boisse +1
We present HST/WFPC2 high-spatial resolution images in the R and B bands of the close environment of the sightlines to seven quasars which spectra show either a damped Ly-alpha abs…
