Cloud-9 under the line-width thermometer: implications for halo concentration and a constraint on Λm³ in superfluid dark matter

Abstract Cloud-9 is a starless, gas-rich dark-matter halo candidate near M94 and a leading candidate for a Reionization-Limited H I Cloud (RELHIC). Its lack of stars removes stellar-feedback explanations for a shallow central potential and makes the H I distribution an unusually clean probe of halo structure. We re-analyse the published VLA column-density profile with two independent reconstruction and modelling pipelines applied to different published representations of the
