THE DATA SET. “There are 670 atomic-cooling haloes, ten of which are metal-free and have not hosted prior star formation. The remaining atomic-cooling haloes have formed stars prompted by either H2 or metal-line cooling and are not conducive to the formation of SMSs (and subsequently direct-collapse black holes, DCBHs).” (SMSs = supermassive black holes).
