Constraining meV Axion Dark Matter with ALMA Observations of the Galactic Center Magnetar SGR 1745-2900
Javier De Miguel, Evanthia Hatziminaoglou, Frédéric Poidevin +4
We report a mm-wave search for axion dark matter from SGR 1745-2900, based on 4.8 h of ALMA observations. No candidate features are found between 133.99-135.78, 135.91-137.70, 145.…
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…
Experimental measurement of the quality factor of a Fabry-Pérot open-cavity axion haloscope
Juan F. Hernández-Cabrera, Javier De Miguel, E. Hernández-Suárez +5
The axion is a hypothetical boson arising from the most natural solution to the problem of charge and parity symmetry in the strong nuclear force. Moreover, this pseudoscalar emerg…
Discovery prospects with the Dark-photons & Axion-Like particles Interferometer
Javier De Miguel, Juan F. Hernández-Cabrera, Elvio Hernández-Suárez +3
We discuss the discovery potential of the Dark-photons & Axion-Like particles Interferometer (DALI) in this letter. The apparatus, currently in a design and prototyping phase, will…
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…
Axion-photon multimessenger astronomy with giant flares
Javier De Miguel, Chiko Otani
We treat prospects for multimessenger astronomy with giant flares (GFs), a rare transient event featured by magnetars that can be as luminous as a hundred of the brightest supernov…
