(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The CO Mapping Array Project (COMAP) aims to use line-intensity mapping of carbon monoxide (CO) to trace the distribution and global properties of galaxies over cosmic time, back to the Epoch of Reionization (EoR). To ...
