Retuning radio astronomy for axion dark matter with neutron stars
Javier De Miguel
A model is constructed to predict the emission originating from axion-to-photon conversion in the strongly magnetized ultrarelativistic plasma of neutron stars. The acceleration an…

DALI sensitivity to streaming axion dark matter
Javier De Miguel, Abaz Kryemadhi, Konstantin Zioutas
Dark matter substructures emerge naturally in a scenario in which the axion angular field acquires propagating degrees of freedom in a post-inflationary Universe. The DALI experime…
