AI generated summary

Planck and ACT cluster abundance implies consistent cosmology

This paper compares galaxy cluster catalogs from Planck and ACT telescopes. It finds their derived cosmological parameters agree when using the same cluster model, implying consistency. Allowing for model evolution, it hints at possible time evolution in clusters or dark energy.
