Exploring the nature of Galactic unassociated sources detected by the Fermi-LAT
F. Acero, A. Acharyya, A. Adelfio +120
We investigate the nature of the unassociated sources detected by the Fermi-LAT close (|b|<10°) to the Galactic plane, representing 16% of all sources in the 4FGL-DR4 catalog. The…
INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, and Vectors
Thong T. Q. Nguyen, Pedro De la Torre Luque, Isabelle John +3
The decay of light bosonic dark matter particles can produce a bright electron/positron () flux that can be strongly constrained by local Voyager observations of the direct…
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…
Sub-keV dark matter can strongly ionize molecular clouds
Pedro De la Torre Luque, Pierluca Carenza, Thong T. Q. Nguyen
We show that the ionization of dense molecular clouds can be used to set strong constraints on dark matter models producing UV/X-ray photons in their annihilation or decay. We plac…
Constraints on Ultra-heavy DM from TeV-PeV gamma-ray diffuse measurements
Manuel Rocamora, Pedro De La Torre Luque, Miguel A. Sánchez-Conde
Recent experiments have measured the Galactic -ray diffuse emission up to PeV energies, opening a window to study acceleration of Galactic cosmic rays and their propagation up…
The cosmic-ray sea explains the Galactic -ray and diffuse emissions from GeV to PeV
Pedro De La Torre Luque, Daniele Gaggero, Dario Grasso +2
The LHAASO collaboration has recently released the spectrum and the angular distribution of the gamma-ray Galactic diffuse emission from 1 TeV to 1 PeV measured with the Kilometer-…
