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…
Correlated signals of ultralight scalar dark matter in pulsar timing
Joshua W. Foster, Kimberly K. Boddy, Jeff A. Dror +5
Pulsar timing arrays (PTAs) are sensitive to ultralight dark matter (ULDM) in the - mass range, with existing datasets already probing otherwise op…
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…
CMB constraints on dark matter-proton scattering: investigating prior-volume effects using profile likelihoods
Maria C. Straight, Tanvi Karwal, José Luis Bernal +1
We present profile-likelihood constraints on velocity-independent dark matter-proton scattering, including cases in which only a fraction of dark matter has such non-gravitational…
Survival of the most compact: the life and death of satellite halos in self-interacting dark matter
David Klemmer, Moritz S. Fischer, Kimberly K. Boddy +2
Self-interacting dark matter (SIDM) models feature short-range interactions between dark matter (DM) particles that lead to larger diversity in the inner parts of galactic rotation…
First galaxy ultraviolet luminosity function limits on dark matter-proton scattering
Hovav Lazare, Ely D. Kovetz, Kimberly K. Boddy +1
Scattering between dark matter (DM) and protons leads to suppressed small-scale fluctuations, with implications for a variety of cosmological observables. In this work, we search f…
