abstract

This review aims at proposing to the field an overview of the Cusp-core problem, including a discussion of its advocated solutions, assessing how each can satisfactorily provide a description of central densities. Whether the Cusp-core problem reflects our insufficient grasp on the nature of dark matter, of gravity, on the impact of baryonic interactions with dark matter at those scales, as included in semi-analytical models or fully numerical codes, the solutions to it can point either to the need for a paradigm change in cosmology, or to to our lack of success in ironing out the finer details of the $\Lambda$CDM paradigm.

  1. Tunneling and tidal stripping in multifield ultralight dark matter halos

    hep-ph 2026-05 unverdicted novelty 7.0

    A semiclassical tunneling model shows that two-field ultralight DM halos have stability bounds that can be relaxed for some density-mass ratios but become more stringent across much of the parameter space compared to ...

  2. Dynamical flattening of halo density cusps by Q-ball dark matter

    hep-ph 2026-07 conditional novelty 6.0

    Interacting Q-ball dark matter flattens NFW cusps via density-dependent mergers that convert rest mass into escaping relativistic dark-sector particles, preferentially in halo centers.

  3. Structure-wide dark matter density depletion induced by local degeneracies

    astro-ph.GA 2024-07 unverdicted novelty 6.0

    Degeneracy-induced depletion from fermionic DM in subhalos creates structure-wide low-density cores consistent with observations, linking profile diversity to formation history.

  4. Cosmological simulations of the same spiral galaxy: satellite properties, the role of baryonic physics and star formation history in shaping dark matter cores/cusps

    astro-ph.GA 2025-09 conditional novelty 5.0

    Satellites that form most of their stars early keep dark matter cusps, while late or continuous star formers develop oscillating cores, so the dwarf diversity problem may be explained by feedback history and tides wit...

  5. Tightening Bounds on Warm Dark Matter with High-Redshift Gamma-Ray Bursts

    astro-ph.HE 2026-07 conditional novelty 4.0

    Using the redshift distribution of 118 luminous Swift GRBs, warm dark matter particles are bounded to mx ≥ 1.3 keV at 95% CL (≥3.4 keV if GRBs exactly trace the SFR).
