SIDM halos accelerate bar formation and growth in disk galaxies through enhanced angular momentum exchange, independent of core formation.
Information-theoretic analysis of TNG50 simulations finds high mutual information (0.4-0.8) between bar and spiral parameters and comparable transfer entropy (0.33-0.42) in both directions, indicating mutual co-regulation.
