Dark matter halo properties from spatially integrated Hi flux profiles

Abstract Resolved rotation curves (RCs) are our best probe of the dark matter distribution around individual galaxies. However their acquisition is resource-intensive, rendering them impractical for large-scale surveys and studies at higher redshift. Spatially integrated Hi flux profiles on the other hand are observationally abundant and also probe dynamics across the whole Hi disc. Despite this, they are typically only studied using the highly compressed linewidth summary statistic, discarding
