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…

Boosting the optical depth to Thomson scattering with primordial black hole evaporation at high redshift

Isaac Sierra, Gabriel P. Lynch, Lloyd Knox +3

BAO and CMB data are somewhat discrepant when interpreted in the context of cdm, discrepancies that show up as a `matter density deficit' and as a `CMB lensing excess'. One pos…

Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing

Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143

We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…

What's the matter with ?

Gabriel P. Lynch, Lloyd Knox

Due to non-zero neutrino rest masses we expect the energy density today in non-relativistic matter, , to be greater than the sum of baryon and cold dark matter densitie…

The BAO-CMB Tension and Implications for Inflation

Elisa G. M. Ferreira, Evan McDonough, Lennart Balkenhol +3

The scalar spectral index is a powerful test of inflationary models. The tightest constraint on to date derives from the combination of cosmic microwave background (CMB…
