Physical neighbourhood of Q9010 (black circle) surrounded by proximate [OIII] emitters from the ASPIRE survey (yellow stars) and LAEs from Wang et al. (2024a, red stars), and LAE-11 (dark blue star). The parallel distance, d_∥, is defined as negative towards the observer. The perpendicular distance, d_⊥, is defined as negative if RA_gal < RA_QSO. We note that LAE-12 is also an [OIII] emitter, and showed with an orange colour. J0910-0414’s ionisation field (yellow shaded yellow region) is depicted anti-clockwise from the observer and depicts the lower limit on its opening angle θ_Q, assuming a bipolar cone geometry. Since both the observer and the double-peaked LAE must be within this region, we can infer that the lower limit of θ_Q > 49.17°.
