Coordinated UV-optical observations of quasars: the evolution of the Lyman absorption
S. Cristiani, E. Giallongo, L. M. Buson +2
The average flux decrement shortward the Ly emission, due to the well-known ``forest'' of absorptions, has been measured in the spectra of 8 quasars. Quasi-simultaneous optical…
