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,…

The SPHEREx Satellite Mission

James J. Bock, Asad M. Aboobaker, Joseph Adamo +111

SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…

The multiphase interstellar medium as a common origin for magnetic misalignment and TB parity violation

Andrea Bracco, Ari J. Cukierman, Raphael Skalidis +1

We present an original data analysis and a physical model that provide new insights into the origin of, and relationship between, two observables of the dusty, polarized Galaxy at…

Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters

A. R. Polish, P. A. R. Ade, Z. Ahmed +89

Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…
