Fast and Credible Likelihood-Free Cosmology with Truncated Marginal Neural Ratio Estimation
Alex Cole, Benjamin Kurt Miller, Samuel J. Witte +4
Sampling-based inference techniques are central to modern cosmological data analysis; these methods, however, scale poorly with dimensionality and typically require approximate or…
The Olympics: A fair ranking of proposed models
Nils Schöneberg, Guillermo Franco Abellán, Andrea Pérez Sánchez +3
Despite the remarkable success of the Cold Dark Matter (CDM) cosmological model, a growing discrepancy has emerged (currently measured at the level of ) between t…
Axion-Photon Conversion in Neutron Star Magnetospheres: The Role of the Plasma in the Goldreich-Julian Model
Samuel J. Witte, Dion Noordhuis, Thomas D. P. Edwards +1
The most promising indirect search for the existence of axion dark matter uses radio telescopes to look for narrow spectral lines generated from the resonant conversion of axions i…
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…
Electromagnetic Signatures of Dark Photon Superradiance
Andrea Caputo, Samuel J. Witte, Diego Blas +1
Black hole superradiance is a powerful tool in the search for ultra-light bosons. Constraints on the existence of such particles have been derived from the observation of highly sp…
Exploring the Origin of Supermassive Black Holes with Coherent Neutrino Scattering
Victor Munoz, Volodymyr Takhistov, Samuel J. Witte +1
Collapsing supermassive stars () at high redshifts can naturally provide seeds and explain the origin of the supermassive black holes observed in…
