Joint kSZ-clustering analysis of ACT DR6 and CMASS yields a halo optical depth profile more extended than Websky simulations, suggesting stronger baryonic feedback.
High-significance kSZ measurements around LRGs show gas is redistributed beyond gravitational collapse and imply more efficient feedback in group-scale halos than in standard hydrodynamical models.
Radio contamination must be jointly fit with tSZ and CIB in unWISE-Planck/ACT cross-spectra; its inclusion yields positive signals to ℓ ≃ 6000 that match a two-parameter generalized NFW pressure profile.
Emulation of binned modified gravity power spectra to <1% accuracy enables MCMC forecasts that constrain μ and η via LSST large-scale structure combined with CMB lensing, with best sensitivity along the lensing combination Σ.
