Core-collapsed SIDM halos produce longer FRB image time delays than CDM halos, enabling future surveys to constrain self-interaction cross sections above roughly 18-40 cm²/g depending on collapse timing.
Two-component SIDM with velocity-dependent inter- and intra-species interactions produces mass segregation that forms dwarf cores and boosts small-scale strong lensing efficiency by a factor of a few.
N-body simulations with Arepo calibrate the β parameter in the SIDM gravothermal model, showing it is independent of cross-section, concentration, and mass for velocity-independent scattering, and introduce an effective β model for the long-mean-free-path regime.
