An unbiased measurement of the UV background and its evolution via the proximity effect in quasar spectra
Aldo Dall'Aglio, Lutz Wisotzki, Gabor Worseck
We used 40 high resolution, high S/N QSO spectra at 2.1<z<4.7 to search for the signature of the proximity effect in the HI Lyalpha forest. Comparing the effective optical depth ne…

The transverse proximity effect in spectral hardness on the line of sight towards HE 2347-4342
G. Worseck, C. Fechner, L. Wisotzki +1
We report the discovery of 14 quasars in the vicinity of HE2347-4342, one of the two quasars whose intergalactic HeII forest has been resolved with FUSE. By analysing the HI and th…
