The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results demonstrate a close correspondence between galaxy and BH cosmic histories. This work provides a comprehensive, simulation-based framework for linking galaxy and BH merger populations.

C2weakest assumption

That the Horizon-AGN simulation accurately reproduces the physical processes of galaxy mergers and black hole dynamics, and that the optimized MCC thresholds correctly isolate physically bound pairs without large projection contamination.

C3one line summary

Horizon-AGN shows galaxy and black hole merger rates both rise with stellar mass and fall with redshift, peaking near z=2-3, establishing a direct evolutionary link from galaxy interactions to black hole coalescences.
