The galaxy-electron cross-spectrum with ACT, SPT-3G and DESILS LRGs

The galaxy--electron cross-power spectrum measures the small-scale distribution of gas around galaxies, the quantity reshaped by feedback. We measure from the…
Optimal and exact wide-angle power spectrum estimation
Noah Sailer, Kendrick Smith, Yurii Kvasiuk +2
What is the optimal power spectrum estimator on ultra-large scales where the plane-parallel approximation breaks down? Conventional estimators, such as the Yamamoto estimator, are…
First detection of the moving lens effect with ACT and DESI LS
Selim C. Hotinli, Kendrick M. Smith, Simone Ferraro +4
The moving lens effect is a secondary CMB anisotropy induced by the transverse motion of gravitational potentials. We develop a Fourier-space cross-spectrum estimator that retains…

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
