The Atacama Cosmology Telescope: Constraints on the anisotropic screening and birefringence effects with DR6
Darby M. Kramer, Alexander van Engelen, Frank J. Qu +14
While we have learned much from recent surveys of the mm-wave sky, many secondary anisotropies of the CMB remain under-explored. We consider two of these here: the anisotropic scre…
Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing
Niall MacCrann, Christopher Cain, Aleksandra Kusiak +5
We investigate the cross-correlation of the kinematic Sunyaev-Zeldovich (kSZ) effect with lensing of the cosmic microwave background (CMB) as a probe of the epoch of reionisation.…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

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 CMB optical depth constrains the duration of reionization
Christopher Cain, Alexander Van Engelen, Kevin S. Croker +3
Recently, it was pointed out that invoking a large value of the CMB optical depth, , could help resolve tensions between DESI DR2 BAO data and the CMB. This is…

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…
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: Reionization kSZ trispectrum methodology and limits
Niall MacCrann, Frank J. Qu, Toshiya Namikawa +20
Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight mo…
The Atacama Cosmology Telescope: A search for late-time anisotropic screening of the Cosmic Microwave Background
William R. Coulton, Theo Schutt, Abhishek S. Maniyar +37
Since the formation of the first stars, most of the gas in the Universe has been ionized. Spatial variations in the density of this ionized gas generate cosmic microwave background…
