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,…

Detecting gravitational lensing by matter currents

C. Murray, R. Kou, J. G. Bartlett

We explore the observational prospects for detecting gravitational lensing induced by cosmological matter currents, a relativistic correction to the standard density lensing effect…

Unified dark fluid with null sound speed as an alternative to phantom dark energy

Raphaël Kou, Antony Lewis

Recent BAO measurements from DESI, when combined with CMB and supernovae data, suggest evolving dark energy and in particular point to a possible phantom regime, with an equation o…

Improving CMB constraints on early Universe physics with LSS: A multi-probe forecast including cross-covariance

Raphaël Kou, Antony Lewis

Extensions to the model prior to recombination can modify the growth of perturbations around radiation-matter equality, leaving a distinct signature in the matter p…

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…
