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…

Primordial Non-Gaussianity and the Field-Level Cramer-Rao Bound
Eugene Chen, Daniel Green, Vincent S. H. Lee
Primordial non-Gaussianity is one of the most powerful probes of the inflationary epoch. The particle spectrum relevant to inflation, including masses and spins, is encoded in the…

New Interpretations of the Cosmological Preference for a Negative Neutrino Mass
Peter W. Graham, Daniel Green, Joel Meyers
Recent observations of the cosmic microwave background (CMB) and baryon acoustic oscillations (BAO) show some tension with a CDM cosmology. For one, the cosmological parameters…
