Properties of QSO host and companion.

QSO Companion
Scont,  253 GHz [mJy] 1.19 ± 0.06 0.25 ± 0.01
Scont,  99 GHz [mJy] 0.043 ± 0.005 0.007 ± 0.002
L[CII] ( * ) [109L] 4.70 1.68
MHI [109M] 6.43 2.30
Tdust [K] 48±2 30–50
Mdust [107 M] 2.3±0.8 0.3–2.6
β 2.6±0.2 2.0–3.1
SFR [M yr−1] 265±32 ( * *) 35–344

Notes. The dust properties and SFR of the QSO host galaxy are taken from Tripodi et al. (2023a). ( * )L[CII] were computed inside a region > 2σ from the [CII] maps shown in the top panels of Fig. 2, as explained in Sect. 3.1. ( * *)The SFR of the QSO host galaxy was corrected by a factor of 50% to account for the possible contribution of the AGN to the dust heating (Tripodi et al. 2023a).
