The DALI Haloscope: A Magnetized Phased Array Coupled to a Semi-Open Fabry--Pérot Resonator
Javier De Miguel, Antonios Gardikiotis, Eduardo David González-Carretero +10
DALI is an axion haloscope consisting of a magnetized phased array backed by a conducting mirror and coupled in the near field to a semi-open Fabry--Pérot resonator. The applied st…
Constraints on Galactic Dark Photons from a DALI Prototype
Javier De Miguel, Antonios Gardikiotis, Elvio Hernández-Suárez +10
An analysis of 36 hours of data from a DALI haloscope reveals no statistically significant excess attributable to dark-photon dark matter. We therefore set new constraints in the 6…
Solar axion searches with RES-NOVA: projected sensitivity and first prototype limit
D. Alloni, G. Benato, P. Carniti +49
RES-NOVA is a cryogenic experiment based on PbWO4 scintillating bolometers produced from archaeological lead, originally designed to detect coherent elastic neutrino-nucleus scatte…
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…
Superdense beaming of axion dark matter in the vicinity of the light cylinder of pulsars
Javier De Miguel, Chiko Otani
In this article we treat the non-adiabatic photon-to-axion resonant conversion of curvature radiation, synchrotron emission and inverse Compton scattering dominating the spectral d…
A dark matter telescope probing the 6 to 60 GHz band
Javier De Miguel-Hernández
In this article we present the Dark-photonsAxion-Like particles Interferometer (DALI), a novel experiment designed for the detection of photon-mixing cold dark matter in the mi…
