It tests whether the leading computer model of galaxy formation can explain the observed mass-size plane correlations, finding a link between stellar age and galaxy spin that ties star formation history to morphology.","discovery_kind":"extension","skeptic_critique":null,"referee_report":null,"author_rebuttal":null,"desk_editor":null,"rs_alignment":null,"lean_confirmation":null,"pith_extraction":null,"created_at":"2026-08-14T15:58:38.568520+00:00","model_set":{"reader":"deepseek-v4-flash"},"falsifier":null,"supporting_citations":[],"review_version":1}
