Spectral shape of the UV ionizing background and HeII absorption at redshifts 1.8 < z < 2.9

I. I. Agafonova, S. A. Levshakov, D. Reimers +4

The shape of the UV ionizing background is reconstructed from optically thin metal absorption-line systems identified in spectra of HE2347-4342, Q1157+3143, and HS1700+6416 in the…
