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…
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…
Refining Galactic primordial black hole evaporation constraints
Pedro De la Torre Luque, Jordan Koechler, Shyam Balaji
We revisit the role of primordial black holes (PBHs) as potential dark matter (DM) candidates, particularly focusing on light asteroid-mass PBHs. These PBHs are expected to emit pa…
Leptophilic dark matter in models: a solution to the Fermi-LAT Galactic Center Excess consistent with cosmological and laboratory observations
Jordan Koechler, Mattia Di Mauro
The particle origin of dark matter (DM) remains elusive despite decades of direct, indirect, and collider searches. Several groups have reported a -ray excess toward the Galact…
Putting all the X in one basket: Updated X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Jordan Koechler +2
Sub-GeV dark matter particles can annihilate or decay producing e^\pm pairs which upscatter the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inver…
