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,…
A halo model of extragalactic contamination to CMB lensing, delensing, and cross-correlations
A. Baleato Lizancos, W. Coulton, A. Challinor +2
CMB lensing reconstructions are a sensitive probe of the growth of structure across cosmic time and a key tool to sharpen investigations of the very early Universe via delensing. A…
LiteBIRD Science Goals and Forecasts: Improving Sensitivity to Inflationary Gravitational Waves with Multitracer Delensing
T. Namikawa, A. I. Lonappan, C. Baccigalupi +119
We estimate the efficiency of mitigating the lensing -mode polarization, the so-called delensing, for the experiment with multiple external data sets of lensing-mass…
LiteBIRD Science Goals and Forecasts: A full-sky measurement of gravitational lensing of the CMB
A. I. Lonappan, T. Namikawa, G. Piccirilli +119
We explore the capability of measuring lensing signals in full-sky polarization maps. With a arcmin beam width and an impressively low polarization noise of $2.16\,…
