A non-parametric higher-order Jeans analysis method, GravSphere, was recently used to constrain the density profiles of Local Group dwarf galaxies, classifying them into those that are more likely to have an inner dark matter cusp and those that are likely to have a core (Read et al.).

We provide a best-fitting contracted NFW halo model to the MW rotation curve that matches the data very well.

EAGLE low-mass discs are non-self-gravitating so the softening plays no role in their vertical structure.

This "cosmic web stripping" may help to explain the scarcity of dwarf galaxies compared with the numerous low-mass halos expected in \Lambda CDM and the large diversity of star formation histories and morphologies characteristic of faint galaxies.
