Abstract Low surface brightness galaxies (LSBs) are an important class of galaxies that allow us to broaden our understanding of galaxy formation and test various cosmological models. We present a survey of low surface brightness galaxies at 0. 4 zphot 0. 8 in the GOODS-S field using JADES data. We model LSB surface brightness profiles, identifying those with ₄₅₅ 24 mag arcsec−2 in the F200W JWST/NIRCam filter. We study the spatial distribution, number density, Sérsic profile parameters, and rest-frame colours of these LSBs. We compare the photometrically-derived star formation histories, mass-weighted ages, and dust attenuations of these galaxies with a high surface brightness (HSB) sample at similar redshift and a lower redshift (zphot 0. 4) LSB sample, all of which have stellar masses ≲ 108M⊙. We find that all samples have low star formation (SFR100 ≲ 0. 01 M⊙ yr−1). The higher redshift LSBs and HSBs have similar star formation histories which show that the LSBs and HSBs possibly come from the same progenitors at z ≳ 2, though the histories are not well constrained for the LSB samples. The LSBs appear to have minimal dust, with most of our LSB samples showing AV 1 mag. JWST has pushed our understanding of LSBs beyond the local Universe.
