However, with Stage IV surveys ($\\textit{e.g. LSST}$ and $\\textit{Euclid}$) imminent, extending mass-mapping techniques to the sphere is a fundamental necessity. As such, we extend the sparse hierarchical Bayesian mass-mapping formalism presented in previous work to the spherical sky. For the first time, this allows us to construct $\\textit{maximum a posteriori}$ spherical weak lensing dark-matter mass-maps, with pri","authors_text":"Jason D. McEwen, L. Pratley, Matthew A.
