The Sun as a target for axion dark matter detection
Elisa Todarello, Marco Regis, Marco Taoso +3
The exploration of the parameter space of axion and axion-like particle dark matter is a major aim of the future program of astroparticle physics investigations. In this context, w…
Constraints on the origin of the radio synchrotron background via angular correlations
Elisa Todarello, Marco Regis, Federico Bianchini +7
The origin of the radio synchrotron background (RSB) is currently unknown. Its understanding might have profound implications in fundamental physics or might reveal a new class of…
Anatomy of astrophysical echoes from axion dark matter
Elisa Todarello, Francesca Calore, Marco Regis
If the dark matter in the Universe is made of eV axion-like particles (ALPs), then a rich phenomenology can emerge in connection to their stimulated decay into two photons. We d…
Updated bounds on Axion-Like Particle Dark Matter with the optical MUSE-Faint survey
Elisa Todarello
Bounds are derived on the axion-like particle (ALP) to two-photon coupling in the mass range eV. The bounds are obtained by searching for the signal from ALP decay in t…
Robust bounds on ALP dark matter from dwarf spheroidal galaxies in the optical MUSE-Faint survey
Elisa Todarello, Marco Regis, Javier Reynoso-Cordova +5
Nearby dwarf spheroidal galaxies are ideal targets in the search for indirect dark matter (DM) signals. In this work, we analyze MUSE spectroscopic observations of a sample of five…
Constraining Below-threshold Radio Source Counts With Machine Learning
Elisa Todarello, Andre Scaffidi, Marco Regis +1
We propose a machine-learning-based technique to determine the number density of radio sources as a function of their flux density, for use in next-generation radio surveys. The me…
