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…

Spontaneously Broken -Form U(1) Symmetries
Daniel Aloni, Eduardo GarcÃa-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…

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…
