8 More than primary Cl… More than primary Cl… Cl -> structures @ z ~ 1000 Cl -> structures @ z ~ 1000 Lensing detected ~ 25 σ (after ACT) Lensing detected ~ 25 σ (after ACT) Lensing -> structures @ z ~ 2 (consistent with predictions of ∧ CDM…) Lensing -> structures @ z ~ 2 (consistent with predictions of ∧ CDM…) A.Benoît-Levy

9 More CMB than with Planck… More CMB than with Planck…
