X-shooter observations of QSO pairs
arXiv:1101.1897 · doi:10.1002/asna.201111546
Abstract
Observations of quasar pairs represent a powerful tool in the study of the intergalactic medium, providing in particular information on the quasar radiative feedback not only along the line of sight, but also in the transverse direction. In this paper, we present the spectra of the four quasar pairs we observed so far with X-shooter, and we discuss two individual spectra affected by the presence of a close quasar in the foreground.
