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

We estimate that up to 8 dark galaxies should be detectable in HI emission within 2.5 Mpc of the MW, with the FAST telescope, accounting for its sky coverage and minimum M_HI and N_HI.

C2weakest assumption

That the chosen star formation density thresholds and baryonic feedback prescriptions in the hydrodynamical simulations correctly capture the conditions under which gas in low-mass halos remains unable to form stars.

C3one line summary

Constrained Local Group hydrodynamical simulations predict up to 8 HI-detectable dark galaxies within 2.5 Mpc of the Milky Way.
