Galaxy rotation curves: flat curves require mass beyond visible disk. Gravitational lensing: mass inferred from light bending exceeds visible mass. Bullet Cluster: separation of X-ray gas from lensing mass in cluster collision. CMB: acoustic peaks encode dark matter to baryon ratio. Structure formation: CDM model successfully predicts large-scale structure.
WIMPs: 10 GeV to 10 TeV mass, weak interaction cross section, thermal relic. Axions: ultralight, motivated by strong CP problem, cavity experiments. Sterile neutrinos: right-handed neutrinos mixing with active neutrinos. Primordial black holes: formed in early universe, constrained but not ruled out. FIMPs: feebly interacting massive particles, freeze-in production mechanism.
Direct detection: nuclear recoil in underground detectors, LUX, XENONnT, PandaX. Indirect detection: annihilation or decay products, gamma rays, neutrinos, positrons. Collider production: missing energy signatures at LHC, monojet events. Astronomical: perturbations to stellar streams, substructure in galaxy halos.
MOND: modified Newtonian dynamics, acceleration-dependent force law. MOND success: fits galaxy rotation curves with one free parameter. MOND failure: galaxy clusters require additional dark matter even with MOND. TeVeS: relativistic MOND extension, difficulties with CMB and gravitational waves.
| Pitfall | Fix |
|---|---|
| WIMP-centric view | Many viable candidates exist at different mass scales |
| Ignoring local density uncertainty | Direct detection rates depend on local DM density |
| Dismissing MOND entirely | Explains individual galaxies well, fails at cluster scale |
| Confusing exclusion limits with detection | Null result sets upper limit only |
