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

highly ejective models under-predict the luminosity of galaxy groups at fixed mass at high significance (5.7σ). This conclusion is robust against selection effects and is obtained from directly measurable and minimally correlated quantities.

C2weakest assumption

That the observed X-ray luminosity-temperature relation in the heterogeneous sample of 44 groups can be compared directly to simulation predictions without substantial biases from selection effects, measurement uncertainties, or differences in how groups are identified.

C3one line summary

Highly ejective feedback models under-predict the X-ray luminosity of galaxy groups at fixed mass at 5.7 sigma significance.
