abstract
We use luminous red galaxies selected from the imaging surveys that are being used for targeting by the Dark Energy Spectroscopic Instrument (DESI) in combination with CMB lensing maps from the Planck collaboration to probe the amplitude of large-scale structure over $0.4\le z\le 1$. Our galaxy sample, with an angular number density of approximately $500\,\mathrm{deg}^{-2}$ over 18,000 sq.deg., is divided into 4 tomographic bins by photometric redshift and the redshift distributions are calibrated using spectroscopy from DESI. We fit the galaxy autospectra and galaxy-convergence cross-spectra using models based on cosmological perturbation theory, restricting to large scales that are expected to be well described by such models. Within the context of $\Lambda$CDM, combining all 4 samples and using priors on the background cosmology from supernova and baryon acoustic oscillation measurements, we find $S_8=\sigma_8(\Omega_m/0.3)^{0.5}=0.73\pm 0.03$. This result is lower than the prediction of the $\Lambda$CDM model conditioned on the Planck data. Our data prefer a slower growth of structure at low redshift than the model predictions, though at only modest significance.

KiDS-Legacy: The consistency test of the large-scale structure with Bernardeau-Nishimichi-Taruya transform
BNT k-cuts on KiDS-Legacy give S8=0.798±0.045 (theory covariance) with no nonlinear bias, while observed-data covariance produces a mild low-k preference for lower S8.

Cosmology from Planck CMB Lensing and DESI DR1 Quasar Tomography
DESI DR1 quasars cross-correlated with Planck PR4 lensing give sigma8 = 0.929 and S8 = 0.922, about 1.5 sigma above Planck's LCDM prediction, and a sound-horizon-free H0 = 69.1 km/s/Mpc.

Low-redshift constraints on structure growth from CMB lensing tomography
Low-redshift galaxy clustering and CMB lensing tomography with hybrid effective field theory gives S8=0.79±0.06, consistent with Planck, while data alone prefer Ωm=0.245±0.024.

Implicit Likelihood Inference of the Neutrino Mass Hierarchy from Cosmological Data
A simulation-based neural-likelihood analysis of Planck 2018 and DESI DR2 data reports a weak preference (tilde_Delta = 0.12, 68% CL interval spanning both signs) for the normal neutrino mass hierarchy.

Reconstructing the shape of the non-linear matter power spectrum using CMB lensing and cosmic shear
A joint ACT DR6 + DES Y3 analysis reconstructs the non-linear matter power spectrum in five k-bins and finds marginal, roughly 2 sigma evidence for scale-dependent suppression that baryonic feedback or ultralight axio...
