Shock-to-shock distances in double radio relic clusters serve as a merger chronometer to set a 68% upper limit of sigma/m < 0.22 cm²/g on dark matter self-interaction, marginalizing over mass, angle, speed, phase, impact parameter, and gas slope.

Optical selection criteria based on brightest cluster galaxy probabilities and separations efficiently identify merging galaxy clusters, validated by new X-ray and spectroscopic observations of twelve candidates.
Simulations indicate LISA could statistically distinguish CDM from SIDM (constant 1 cm²/g cross-section) with at least ~70 high-SNR massive black hole merger detections.
