- W2512001330 abstract "Spectroscopic UV observations with the Hubble Space Telescope of the QSO HS 1700+6416 (z = 2.72) (Reimers et al. 1992, 1993) offer for the first time the possibility to measure column densities of C, N and O simultaneously in several ionization stages (O III to O VI, C III and C IV, N II to N V). Photoionization models have been computed and fitted to observed column density ratios of three heavy-element systems (z = 1.8465, 2.1678, 2.433) in order to constrain the shape and intensity of the ionizing background radiation field. An optimal fit to observed ion column densities for each of the three redshift systems is obtained for an ionizing power law continuum with α = −0.6 (f v ∼ ν α ), while −0.1 ≥ α ≥ −1.5 is still consistent with the data" @default.
