Balmer break strength measurements versus redshift for galaxies with secure spectroscopic redshifts. The gray area shows BB≤1, often referred to as a Balmer jump. The green circles show the sources in this work, and the dashed green line is the median BB obtained in three redshift intervals used in this work. All BB measurements are from photometry, and the upper limits are 3σ. The BB measurements by Roberts-Borsani et al. (2024) using stacked JWST spectra are shown by the dash-dotted black line. For comparison, the dotted blue line shows our photometric BB measurements based on the same spectra, obtained from synthetic photometry using the same filters as for our sample. BB objects from the literature are shown in magenta (Vikaeus et al. 2024; Looser et al. 2024; Boyett et al. 2024; Witten et al. 2024; Wang et al. 2024a); for these objects, we also show our BB measurements from photometry (green circles with dark border).
