JADES: low surface brightness galaxies at 0.4 < z < 0.8 in GOODS-S

Journal article

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 LSBs at in the Great Observatories Origins Deep Survey-South (GOODS-S) field using JWST Advanced Deep Extragalactic Survey (JADES) data. We model LSB surface brightness profiles, identifying those with mag arcsec in the F200W James Webb Space Telescope/Near-Infrared Camera (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 () LSB sample, all of which have stellar masses . We find that all samples have low star formation (SFR). 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 , 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 mag. JWST has pushed our understanding of LSBs beyond the local Universe.
