Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing

Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143

We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…

The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth

Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155

We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…

The Atacama Cosmology Telescope: A demonstration of CMB lensing measurement from daytime data

Irene Abril-Cabezas, Frank J. Qu, Joshua Kim +30

We present a cosmic microwave background (CMB) lensing power spectrum analysis using daytime data (11am-11pm UTC) gathered by the Atacama Cosmology Telescope (ACT) over the period…

Probing inflationary gravitational waves with cross-correlations: improved forecasting and validation with simulations

Toshiya Namikawa, Irene Abril-Cabezas, Blake D. Sherwin

We present a follow-up study to the method recently proposed by Namikawa and Sherwin (2023) to probe gravitational waves using cross-correlations between two cosmic microwave backg…

The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope

The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419

We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
