FEASTS Compared with Simulations: Abnormally Irregular and Extended H i Morphologies at a Column Density of 1018 cm−2 in TNG50 and Auriga

With new atomic-hydrogen (H i ) observations of FAST Extended Atlas of Selected Targets Survey (FEASTS), we present the first statistical comparison of H i morphology between observations and cosmological simulations, focusing on low-column-density (∼10 ^18 cm ^−2 ) regions of Milky Way–like central...
