Inflationary Axion Isocurvature in the CMB across All Ultralight Masses

Rayne Liu, Wayne Hu, Daniel Grin

If the Peccei-Quinn symmetry of an ultralight axion is broken before the end of inflation, axion quantum fluctuations seed isocurvature perturbations, linking them to the tensor-to…

Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics

Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33

Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…

Accurate method for ultralight axion CMB and matter power spectra

Rayne Liu, Wayne Hu, Daniel Grin

Ultralight axions (ULAs) with masses are well motivated in string-inspired models and can be part or all of the dark energy or the…

Extreme Axions Unveiled: a Novel Fluid Approach for Cosmological Modeling

Harrison Winch, Renee Hlozek, David J. E. Marsh +2

Axion-like particles (ALPs) are a well-motivated dark matter candidate that solve some of the problems in the clustering of large scale structure in cosmology. ALPs are often descr…

A cosmic microwave background search for fine-structure constant evolution

Hurum Maksora Tohfa, Jack Crump, Ethan Baker +4

In some extensions of the standard model of particle physics, the values of the fundamental coupling constants vary in space and time. Some observations of quasars hint at time and…

CMB-S4: Forecasting Constraints on Through -distortion Anisotropy

David Zegeye, Federico Bianchini, J. Richard Bond +14

Diffusion damping of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. At redshift $5 \times 10^4…
