NIRSpec PRISM spectra of selected strong BB candidates at z ∼ 7 − 9.6, showing objects with clear or plausible BBs. Binned and unbinned spectra are shown for illustration. For comparison, we also overplot the spectrum of the mini-quenched z = 7.3 galaxy from Looser et al. (2024), redshifted and rescaled to approximately match the observed flux blueward of the BB. Top left: Clear BB galaxy at z = 7.26 (object in Vikaeus et al. 2024). Top right: BB galaxy at z = 7.48. Bottom left: BB candidate at z = 8.53. Bottom right: BB candidate at z = 9.56.
