Abstract

In November 2022, the ESA Science Programme Committee (SPC) selected ARRAKIHS as the second Fastimplementation mission (F2) within the Agency’s Scientific Programme, with a launch planned in 2030. ARRAKIHS is designed specifically to explore, at unprecedented depth, the predictions of the Λ-Cold Dark Matter (ΛCDM) cosmological model, and to assess the significance of reported tensions between model and observations in the local Universe. Through multi-band, ultra-low surface brightness imaging of the halos of a statistically representative sample of nearby Milky Waytype galaxies, ARRAKIHS will provide key tests with which to probe both the nature of Dark Matter in the Universe, and baryonic physics currently adopted in state-of-the-art galaxy formation models. This paper describes the ARRAKIHS mission concept and the main design and implementation challenges.
