Self-interacting dark matter increases the Euler characteristic of the reionization ionization field by 60-70% for cross-sections above 2 cm2/g through changes in ionizing source populations.
Strongly interacting dark matter described by a first-principles G2 gauge-theory equation of state can be mixed into neutron stars while remaining compatible with current observational constraints.
MCMC fits of degenerate fermionic dark matter models to eight classical dwarf spheroidal galaxies constrain fermion masses to 100-300 eV and show current data do not strongly favor interacting over non-interacting equations of state.
A minimal electrophilic ALP portal for SIMP pion dark matter widens the allowed parameter space, making an ALP mass of order 10 MeV viable and consistent with the X17 anomaly.
A gauged U(1)_{Lμ-Lτ} model generates nearly degenerate Majorana dark matter whose self-interactions via a light scalar mediator set the relic density, resolve core-cusp anomalies, and fit LZ direct detection plus muon g-2 bounds.
A parameter space analysis of a leptophilic scalar mediator model for Majorana dark matter yields a viable sub-GeV region after applying relic density, cosmological, astrophysical, and laboratory constraints.
