The superclustering of hot gas: cosmological sensitivity in the Websky simulations
M. Lokken, J. R. Bond, R. Hložek +3
Combinations of galaxy surveys and cosmic microwave background secondaries, such as the thermal Sunyaev-Zel'dovich (tSZ) effect, are increasingly being used to jointly constrain co…
Time-dependent deflection reconstruction: new technique to search for gravitational waves with the cosmic microwave background
Alvin Leluc, Joel Meyers, Alexander van Engelen
Gravitational waves (GWs) passing through the Earth cause a correlated pattern of time-dependent deflections of the apparent position of astronomical sources. We build upon standar…
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…
Cross-correlating the patchy screening and kinetic Sunyaev-Zel'dovich effects as a new probe of reionization
Darby Kramer, Alexander van Engelen, Christopher Cain +5
The kinetic Sunyaev-Zel'dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a…
The Atacama Cosmology Telescope: DR6 Power Spectrum Foreground Model and Validation
Benjamin Beringue, Kristen M. Surrao, J. Colin Hill +28
We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (A…
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…
