Astrophysical and Cosmological Probes of Dark Matter
Kimberly K. Boddy, Mariangela Lisanti, Samuel D. McDermott +16
While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remain…
The Hubble Tension as a Hint of Leptogenesis and Neutrino Mass Generation
Miguel Escudero, Samuel J. Witte
The majoron, a neutrinophilic pseudo-Goldstone boson conventionally arising in the context of neutrino mass models, can damp neutrino free-streaming and inject additional energy de…
Quenching Mechanisms of Photon Superradiance
Diego Blas, Samuel J. Witte
Rapidly rotating black holes are known to develop instabilities in the presence of a sufficiently light boson, a process which becomes efficient when the boson's Compton wavelength…
Could the Hubble Tension be Pointing Towards the Neutrino Mass Mechanism?
Miguel Escudero, Samuel J. Witte
Local measurements of the Hubble constant currently disagree with the high-precision value that is inferred from the CMB under the assumption of a CDM cosmology. The significanc…
A Systematic Study of Hidden Sector Dark Matter: Application to the Gamma-Ray and Antiproton Excesses
Dan Hooper, Rebecca K. Leane, Yu-Dai Tsai +2
In hidden sector models, dark matter does not directly couple to the particle content of the Standard Model, strongly suppressing rates at direct detection experiments, while still…
The Cosmological Evolution of Light Dark Photon Dark Matter
Samuel D. McDermott, Samuel J. Witte
Light dark photons are subject to various plasma effects, such as Debye screening and resonant oscillations, which can lead to a more complex cosmological evolution than is experie…
