A comparison of the profiles of photospheric absorption lines (C IIIλ1247, O Vλ1371, Si IIλ1485, and S Vλ1502) to He IIλ1640 and [C I] (2–1) emission lines. PKS 0529-549 has an asymmetric He IIλ1640 emission line profile, consisting of two possible absorbers over a broad emission line and/or multiple narrower emission line components. This is in stark contrast with other high-redshift radio galaxies whose He II emission is dominated by broad emission. Note that the He II absorption at ∼300 km s⁻¹ is affected by faint sky lines and thus is not considered to be a real feature here. The red and blue lines are the [C I] spectra extracted from two separate regions from the ALMA cube (Table 4). Note that the photospheric lines might consist of multiple velocity components corresponding to the He II emission or absorption lines, or they might be resolved into multiplets. The X-shooter spectrum has been normalized to its continuum, Gaussian smoothed, and arbitrarily shifted upwards for easier visualization.
