The proposed model posits that a type of dark matter made up of fermions can form a dense core nested within a more diffuse halo.
Notes on verification
Directly corroborated by the peer-reviewed source paper (Crespi et al. 2026, MNRAS), the RAS press release, and numerous independent science journalism outlets, all describing the same fermionic dark matter core-halo model.
