abstract
CMB lensing tomography, or the cross-correlation between CMB lensing maps and large-scale structure tracers over a well-defined redshift range, has the potential to map the amplitude and growth of structure over cosmic time, provide some of the most stringent tests of gravity, and break important degeneracies between cosmological parameters. In this work, we use the unWISE galaxy catalog to provide three samples at median redshifts $z \sim 0.6, 1.1$ and 1.5, fully spanning the Dark Energy dominated era, together with the most recent Planck CMB lensing maps. We obtain a combined cross-correlation significance $S/N = 79.3$ over the range of scales $100 < \ell < 1000$. We measure the redshift distribution of unWISE sources by a combination of cross-matching with the COSMOS photometric catalog and cross-correlation with BOSS galaxies and quasars and eBOSS quasars. We also show that magnification bias must be included in our analysis and perform a number of null tests. In a companion paper, we explore the derived cosmological parameters by modeling the non-linearities and propagating the redshift distribution uncertainties.

Bias hardened estimators of patchy screening profiles
The authors derive and validate lensing-hardened estimators for stacked patchy screening measurements, show the unmitigated lensing bias dominates the ACT x unWISE signal, and place an upper bound on the screening amplitude.

Tomographer: End-to-end Redshift Distribution Estimation for Source Catalogs and Intensity Maps
Tomographer recovers bias-weighted redshift distributions b(z)dN/dz or b(z)dI/dz from source catalogs or intensity maps in minutes, using precomputed activation maps instead of user-side pair counting.

Constraints on the remote quadrupole field from the polarized Sunyaev Zel'dovich effect
A first pSZ bispectrum search with Planck/ACT and unWISE/CIB data finds no signal, giving b_q=1.02±2.64 and τ_rei=−0.01±0.14.

Velocity Reconstruction from KSZ: Measuring $f_{NL}$ with ACT and DESILS
The first 3D velocity reconstruction from a photometric galaxy survey detects the galaxy-velocity power spectrum at 11.7 sigma and constrains fNL = -39 +40/-33.

Mapping the gas density with the kinematic Sunyaev-Zel'dovich and patchy screening effects: a self-consistent comparison
A 7.2-sigma kSZ detection and a 4.1-sigma patchy screening signal around DESI LRGs, with the screening signal attributed mostly to CMB lensing, leaving a 95% upper limit tau < 2.5e-4 for the gas optical depth.

Tuning the cosmic instrument: robust cosmology through combined probes
Low-redshift large-scale structure data pull the dark-energy equation-of-state posterior toward a cosmological constant and yield S8=0.777±0.017.

Tomographic analyses of the CMB lensing and galaxy clustering to probe the linear structure growth
Tomographic cross-correlation of Planck CMB lensing with SCUSS/SDSS/WISE galaxies yields a linear growth amplitude A_D = 1.16 ± 0.13, consistent with ΛCDM.

The Status of Single Scalar Field Dark Energy
Cosmological data can constrain only a handful of EFT parameters for single-scalar dark energy; extended models show modest preference over Λ but remain underdetermined and challenged by fifth forces and screening.
