We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

The study of polarized dust emission has become entwined with the analysis of the cosmic
microwave background (CMB) polarization in the quest for the curl-like B-mode polarization …

We present a detailed overview of the science goals and predictions for the Prime-Cam
direct-detection camera–spectrometer being constructed by the CCAT-prime collaboration …

The Probe of Inflation and Cosmic Origins (PICO) is an imaging polarimeter that will scan the
sky for 5 years in 21 frequency bands spread between 21 and 799 GHz. It will produce full …

Recent analyses of 21 cm neutral hydrogen (H i) emission have demonstrated that H i gas is
organized into linear filamentary structures that are preferentially aligned with the local …

If a single line of sight (LOS) intercepts multiple dust clouds with different spectral energy
distributions and magnetic field orientations, then the frequency scaling of each of the …

Galactic foregrounds are the main obstacle to observations of the cosmic microwave
background (CMB) B-mode polarization. In addition to obscuring the inflationary B-mode …

Interstellar dust is an essential component of the interstellar medium (ISM) and plays critical
roles in astrophysics. Achieving an accurate model of interstellar dust is therefore of great …

Multi-messenger astronomy, the coordinated observation of different classes of signals that
originate from the same astrophysical event, provides a wealth of information about …

Accurate characterization of the polarized dust emission from our Galaxy will be decisive in
the quest for the cosmic microwave background (CMB) primordial B-modes. An incomplete …
