Image Details
Caption: Figure 8.
Radial profiles of the stacked rest-frame UV (1500–2000 Å) images of photometrically selected LRDs from P. Rinaldi et al. (2025a), shown in redshift bins. For comparison, the nominal PSFs are overplotted: F115W for z ≈ 4–5.8 and F150W for z ≈ 5.8–8. A slight increase in radial extent is observed when moving from the highest to the lowest redshift bin.
