Three-dimensional visualisation of the complex of spectroscopically confirmed z ∼ 5.9 galaxies situated along the line of sight. JADES sources are shown by hexagons, FRESCO sources by squares, and MUSE sources by circles. Many of the objects in JADES and MUSE are observed to be LAEs (indicated by large grey squares). For the six LAEs observed in JADES, ionised bubbles whose sizes were inferred under the assumption that (see Sect. 3.1) are shown by wireframe spheres centred on each LAE (see also annotations). Galaxies contained within the ionised bubble of the main z = 5.937 LAE considered here (ID 6002) are indicated with filled markers (open markers otherwise); all sources are furthermore coloured according to their absolute UV magnitude MUV. The inset in the top right corner illustrates the bubble size calculation discussed in Sect. 3.2 (see also Saxena et al. 2023b). It shows the predicted bubble size
for ID 6002 as a function of time since an ionising source has turned on, t*, for a range of LyC escape fractions (1%, 5%, 10%, and 20%), either for the LAE itself (dashed lines) or all sources within its required bubble size. This simple calculation indicates that the neutral hydrogen fraction outside the ionised bubble is likely
, as expected at z ∼ 5.9 (Sect. 3.3).
