MUV-versus-redshift plot for BulletArc-z11 (star) and the spectroscopically confirmed sources from the literature (circles, collated in G. Roberts-Borsani et al. 2025). Fill colors represent magnification μ given by the color bar. Open circles are blank-field sources with μ = 1. MUV values for different characteristic luminosities L* (at z ∼ 10, taken from C. J. Willott et al. 2024) are shown as dashed horizontal lines. The uncertainty on MUV for BulletArc-z11 is partly hidden behind the symbol and includes lensing uncertainties.
