Mixing electromagnetic radiation with dark radiation between BBN and recombination dilutes the baryon-to-entropy ratio, tightening the allowed total extra radiation to at most ~25% more than dark-radiation-only scenarios.
ACT DR6 CMB lensing map gives σ8 = 0.819 ± 0.015 and H0 = 68.3 ± 1.1 km/s/Mpc, consistent with Planck ΛCDM but 1.7-2.1σ higher in S8 than KiDS, DES, and HSC galaxy surveys.
Void x CMB lensing from Roman mocks is robust to catalog construction choices and forecasts S/N of 13-31 sigma with Planck, SO, and CMB-S4-like data for 2D and 3D voids.
Cycle-GANs trained on dust and HI data generate CO maps whose angular power spectra and Minkowski functionals match those of Planck-observed CO lines.
Next-generation CMB experiments are expected to detect thousands of strongly lensed galaxies to z~6 and proto-clusters, plus tens of thousands of local dusty galaxies and radio sources, enabling new studies of galaxy formation.
