Radio spectra of OH471 and OQ172

RADIO spectra for the highly redshifted z ≥ 3.40 quasars OH471 (ref. 1) and OQ172 (ref. 2) are presented here for frequencies between 16.7 MHz and 85.3 GHz. The spectra are complex. Both have a peak at or near 1.4 GHz and a second peak near or above 85 GHz. Both have a low frequency cutoff, the one...
