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

The combined feedback reproduces key observables, including cold gas mass, star formation rate, thermodynamic radial profiles, and black hole growth, while jet-only or wind-only models fail. The success arises from turbulence driven by jet-wind shear that enhances kinetic-to-thermal energy conversion, boosting heating efficiency by factors of three and six relative to wind-only and jet-only cases, respectively.

C2weakest assumption

The jet and wind properties injected into the hydrodynamic simulation are accurately set by general relativistic magnetohydrodynamic simulations of black hole accretion and by observations, and the idealized no-merger relaxed cluster setup is sufficient to capture the dominant physics of a real system like Perseus.

C3one line summary

An idealized simulation of a relaxed Perseus-like cluster shows that combined jet-wind AGN feedback, with GRMHD-constrained properties, reproduces key observables by boosting heating efficiency through shear-driven turbulence.
