Resonant Conversion of Wave Dark Matter in the Ionosphere
Carl Beadle, Andrea Caputo, Sebastian A. R. Ellis
We consider resonant wave-like dark matter conversion into low-frequency radio waves in the Earth's ionosphere. Resonant conversion occurs when the dark matter mass and the plasma…
Pulsar Nulling and Vacuum Radio Emission from Axion Clouds
Andrea Caputo, Samuel J. Witte, Alexander A. Philippov +1
Non-relativistic axions can be efficiently produced in in the polar caps of pulsars, resulting in the formation of a dense cloud of gravitationally bound axions. Here, we investiga…
A new source for light dark matter isocurvature in low scale inflation
Andrea Caputo, Michael Geller, Giuseppe Rossi
Light scalar and pseudoscalar particles are compelling dark matter candidates, with a vast running experimental program to discover them. Previous studies have shown that these lig…
Stellar limits on scalars from electron-nucleus bremsstrahlung
Salvatore Bottaro, Andrea Caputo, Georg Raffelt +1
We revisit stellar energy-loss bounds on the Yukawa couplings of baryophilic and leptophilic scalars . The white-dwarf luminosity function yields $g_{\rm B}\lesssi…
The Second Radio Synchrotron Background Workshop: Conference Summary and Report
J. Singal, N. Fornengo, M. Regis +24
We summarize the second radio synchrotron background workshop, which took place June 15-17, 2022 in Barolo, Italy. This meeting was convened because available measurements of the d…
Dark Matter prospects with COSI: ALPs, PBHs and sub-GeV Dark Matter
Andrea Caputo, Michela Negro, Marco Regis +1
We study the prospects in the search of dark matter offered by the newly selected NASA MeV mission COSI (Compton Spectrometer and Imager). This instrument is designed and optimized…
