A geometric origin for the radiative neutrino portal to secluded dark matter
Mattia Di Mauro
We study a secluded dark-matter scenario in which the smallness of laboratory signals is linked to the origin of neutrino masses. In the four-dimensional theory, the dark sector co…
Refined anti-proton and anti-deuteron fluxes from weak-scale Dark Matter
Marco Cirelli, Mattia Di Mauro, Arpan Kar
We provide the cosmic-ray (CR) fluxes of antiprotons and antideuterons produced by the Galactic annihilation or decay of weak-scale dark matter (DM) particles of masses in the rang…
Toward universal coalescence models for antideuteron production
Mattia di Mauro, Jordan Koechler, Lorenzo Stefanuto +3
Cosmic-ray (CR) antinuclei, especially antideuteron and antihelium-3 nuclei , are among the most promising messengers for indirect dark ma…
A Precise Measurement of the Fermi-LAT Galactic Center Excess Morphology and Spectrum
Mattia Di Mauro
We present a new Fermi-LAT analysis of the Galactic-center excess (GCE) designed to substantially reduce the dominant systematic uncertainties associated with interstellar-emission…
Strong Constraints on Millisecond Pulsar Injection Spectra from Fermi-LAT Observations of the Galactic Center
Jordan Koechler, Pedro De la Torre Luque, Mattia Di Mauro
Millisecond pulsars (MSPs) are a leading explanation of the Galactic Center excess (GCE) observed in Fermi-LAT data. We constrain this scenario by jointly modeling prompt and inver…
Revisiting predictions for cosmic-ray antinucleon fluxes from Galactic Dark Matter
Lorenzo Stefanuto, Mattia Di Mauro, Fiorenza Donato +3
The data on cosmic antiprotons have reached an outstanding precision on energies spanning from GeV to hundreds of TeV, thanks to the space-based AMS-02 experiment. The balloon-born…
