Evaporating Axion Dark Matter and the Hubble Constant
Daniel Aloni, Hengameh Bagherian, Rashmish K. Mishra
Axion-like particles are a well-motivated dark matter candidate that can form a condensate with low momentum and high occupation number. In the presence of dark radiation, this con…
Cosmological probes of Dark Radiation from Neutrino Mixing
Itamar J. Allali, Daniel Aloni, Nils Schöneberg
Models of stepped dark radiation have recently been found to have an important impact on the anisotropies of the cosmic microwave background, aiding in easing the Hubble tension. I…
Spontaneously Broken -Form U(1) Symmetries
Daniel Aloni, Eduardo García-Valdecasas, Matthew Reece +1
Spontaneous breaking of symmetries leads to universal phenomena. We extend this notion to -form U(1) symmetries. The spontaneous breaking is diagnosed by a dependence of the…
Dark Radiation from Neutrino Mixing after Big Bang Nucleosynthesis
Daniel Aloni, Melissa Joseph, Martin Schmaltz +1
A light ( MeV) dark fermion mixing with the Standard Model neutrinos can naturally equilibrate with the neutrinos via oscillations and scattering. In the presence…
Revisiting leptonic nonunitarity
Daniel Aloni, Avital Dery
In the presence of extra neutrino states at high scales, the low-energy effective leptonic mixing matrix (LMM) is in general nonunitary. We revisit the question of what…
A Step in Understanding the Tension
Melissa Joseph, Daniel Aloni, Martin Schmaltz +2
Models of dark sectors with a mass threshold can have important cosmological signatures. If, in the era prior to recombination, a relativistic species becomes nonrelativistic and i…
