X-ray to bolometric luminosity ratio (L_bol/L_X) against L_bol. The four Chandra targets are indicated by red squares. The diamond symbol shows the result of stacking the four. Cyan crosses are those for the individual objects (diamond for stack) where L_bol was estimated from broad Hα (see Table 3). Blue triangles indicate JWST-selected AGNs from Maiolino et al. (2025), where L_bol/L_X values are all lower limits, as X-ray emission was detected from none of these sources. Data for broad-line quasars (Lusso et al. 2020) are shown in a two-dimensional grey-scale histogram.
