A deep X-ray look to the most obscured quasar at z ∼ 3.6 and its environment

Fig. 6.

Spectroscopically derived N_H vs. L_bol for a sample of luminous and X-ray obscured QSOs with $L_{bol} > 10^{47} erg s^{- 1}$ $\rm L_{\mathrm{bol}} > 10^{47}\,\mathrm{erg \, s^{-1}}$ . The filled and empty red stars indicate the BORUS and MYTORUS parameterizations, respectively. The Hot DOGs are represented with stars of different colors (blue for Assef et al. 2016, orange for Vito et al. 2018, and black for Zappacosta et al. 2018).
