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 analysis identifies 12 shear-selected overdensities spanning masses from M_{200}=(0.2--2.2)×10^{14} M_⊙, with a median mass of M_{200}=5.5×10^{13} M_⊙, demonstrating the strong capability of NIR WL for measuring low-mass systems.

C2weakest assumption

The assumption that the measured shear signals primarily trace the mass of the overdensities with negligible contamination from intrinsic galaxy alignments, photometric redshift errors, or line-of-sight projections, and that spatial coincidence with X-ray centroids reliably confirms collapsed structures.

C3one line summary

First near-IR weak-lensing analysis of CANDELS fields detects 12 shear-selected overdensities with masses 0.2-2.2 x 10^14 solar masses at redshifts 0.22-0.9 and mean z=0.68.
