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…
The Rise and Fall of Acoustic Oscillations at Cosmic Dawn
Hector Afonso G. Cruz, Gabriele Montefalcone, Julian B. Muñoz +2
Cosmic dawn 21-cm observations will extend standard-ruler cosmology into the first billion years, unlocking epochs inaccessible by the cosmic microwave background and large-scale s…
WIMP-like Dark Matter Without Thermalization At Freeze-Out
Dan Hooper, Gordan Krnjaic, Gabriele Montefalcone
In the standard thermal relic scenario, dark matter remains in chemical equilibrium with the Standard Model radiation bath until freeze-out occurs at , where i…
CMB Limits on the Absorption of Light Vector and Axial-Vector Dark Matter
Gabriele Montefalcone, Nicola Bellomo, Kimberly K. Boddy
Leptophilic sub-MeV spin-1 dark matter (DM) can be converted into a photon via inelastic scattering with a free electron or absorption by a neutral hydrogen atom in the primordial…
Parameterizing Dark Energy at the density level: A two-parameter alternative to CPL
Gabriele Montefalcone, Richard Stiskalek
We introduce a minimal two-parameter formulation of the dark energy (DE) density evolution normalized to its present-day value, ,…
Directly Probing Neutrino Interactions through CMB Phase Shift Measurements
Gabriele Montefalcone, Subhajit Ghosh, Kimberly K. Boddy +2
Perturbations in the cosmic neutrino background produce a characteristic phase shift in the acoustic oscillations imprinted in the anisotropies of the cosmic microwave background (…
