The Sculptor dwarf spheroidal galaxy is noticeably flattened in projection and hosts at least two chemically and kinematically distinct stellar populations embedded in a common dark halo, yet its line-of-sight and proper-motion kinematics favor a cored inner mass profile and only mild rotation, inconsistent with the steep cusps generically predicted for low-mass ΛCDM subhalos (Battaglia et al. 2008; Walker & Peñarrubia 2011). At the same time, detailed axisymmetric Jeans and chemo-dynamical models show that the inferred dark-matter slope and the degree of flattening are highly sensitive to unknown inclination and anisotropy, so fitting Sculptor’s ellipticity, multiple populations, and velocity structure without fine-tuning halo shape, feedback history, and viewing angle remains a non-trivial small-scale challenge for ΛCDM (Breddels & Helmi 2013; Read et al. 2019).
