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…
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…
Time-dependent deflection reconstruction: new technique to search for gravitational waves with the cosmic microwave background
Alvin Leluc, Joel Meyers, Alexander van Engelen
Gravitational waves (GWs) passing through the Earth cause a correlated pattern of time-dependent deflections of the apparent position of astronomical sources. We build upon standar…
Running the small-correlated-against-large estimator at scale: Applications of small-scale CMB lensing estimators on realistic simulations
Victor C. Chan, Renée Hložek, Joel Meyers +1
The Small-Correlated-Against-Large Estimator (SCALE) for small-scale lensing of the cosmic microwave background (CMB) provides a novel method for measuring the amplitude of CMB len…
