LyC emission of J1316+2614 from the HST/F410M image (0.8″ × 0.8″; north is up, and east is to the left). The continuum-subtracted Lyα emission is shown in blue with three contours representing the 2.5σ − 5σ, 5σ − 8σ, and 8σ − 15σ levels. The emission from the non-ionising UV (F775W, λ₀ ≃ 1650 Å) is represented in orange and has a size corresponding to its observed FWHM (≃0.09″). Top right: GTC optical and near-IR spectra analysed in Marques-Chaves et al. (2022), highlighting the Lyαλ1216 Å (blue) and [O III] λ5008 Å (violet) spectral profile at rest velocities. Bottom right: Normalised (to their maxima) radial profiles obtained for the LyC (black), UV (orange), and Lyα emission (blue).
