Claims

C1strongest claim

We find that the growth history is highly sensitive to the choice of IR cutoff. Models based on the future event horizon are consistent with observational data and can provide a fit comparable to, or slightly better than, the ΛCDM model for suitable values of the Tsallis parameter δ. In contrast, models constructed using the particle horizon generally fail to reproduce the observed growth of structure.

C2weakest assumption

The assumption that the Tsallis parameter δ can be freely adjusted to fit the data without additional theoretical constraints, and that the linear perturbation analysis accurately captures the relevant physics without higher-order effects.

C3one line summary

THDE models with future event horizon IR cutoff match observed cosmic structure growth rates comparably to ΛCDM, whereas particle horizon versions do not.
