Properties of Early Galaxy Candidates from JWST

Caption

Based on the standard model of cosmology, astronomers predict what fraction of the atoms in the universe (vertical axis) are contained in galaxies with a certain mass of stars or higher (horizontal axis). In this study, three galaxy candidates (indicated by a single point spread) appear to be using up a much larger fraction of available atoms for stars than expected. Instead of about 10% as is usual (blue arc), the data suggest these galaxy candidates have converted 100% of available atoms into stars.
