modeling of Galactic dust polarized CMB foreground
Alexei G. Kritsuk, Ka Wai Ho, Ka Ho Yuen +1
We present the analysis of high-resolution synthetic dust polarization maps derived from large-scale simulations of magnetized multiphase interstellar turbulence carried out with t…
The Shocking Origin of the Flat Ratio
Raphael Flauger, Alexei G. Kritsuk, Guanhao Sun
Polarized emission from dust and synchrotron radiation from the ISM are the dominant foregrounds for CMB polarization and are a major challenge for extracting the primordial signal…
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 critical value of the inflationary tensor-to-scalar ratio from inhomogeneous inflation
Panagiotis Giannadakis, Matthew Elley, Raphael Flauger +1
We show that, for a given fixed value of the number of e-folds of the homogeneous solution, inflation succeeds with order unity inhomogeneities in the initial conditions above a ch…
Statistical signatures of interstellar turbulence in dust polarization maps
Ka Wai Ho, Ka Ho Yuen, Raphael Flauger +1
We present results from a high-resolution interstellar turbulence simulation and show that it closely reproduces recent measurements. Our model captures the scaling of $EE…
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…
