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

Among all the spectroscopically confirmed dual AGN in the literature, 27 pairs have projected separations below 7 kpc in this redshift regime, and our sample accounts for 22% of the total.

C2weakest assumption

That the Gaia multipeak selection plus MUSE spectroscopy reliably distinguishes true dual AGN and lensed systems from contaminants, and that selection effects have been correctly accounted for when analyzing distributions as a function of magnitude and separation.

C3one line summary

High-resolution MUSE observations of 30 Gaia multipeak targets confirm 19 AGN multiplets including 6 dual AGN, accounting for 22% of known close pairs below 7 kpc and showing the selection method's efficiency.
