Low-energy antinuclei measurements for background-free indirect dark matter searches and PBH signatures
Tsuguo Aramaki, Ilias Cholis, Philip von Doetinchem +7
Light low-energy cosmic ray antinuclei constitute powerful probes for detecting dark matter or other sources of new physics in our Galaxy. This ASTRA Initiative Mission Concept rev…
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…
Enhanced Cosmic-Ray Antinuclei Fluxes with Dark Matter Annihilation into SUEPs
Mattia Di Mauro, Caleb Gemmell, Austin Batz +4
Standard-Model (SM) hadronic parton showers initiated by secondary cosmic-ray production or dark matter (DM) annihilations robustly predict very low antinuclei yields and a strong…
A wide-field X-ray search for the Geminga pulsar halo with SRG/ART-XC
Roman Krivonos, Silvia Manconi, Vadim Arefiev +8
Searches for the putative large-scale X-ray halo around the Geminga pulsar have been extensively performed using various narrow field-of-view X-ray telescopes. In this paper, we pr…
Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The Galactic Center (GC) is potentially hosting the largest indirect signal from particle dark matter (DM), which in many well-motivated models would produce gamma rays as their fi…
The gamma-ray emission from Radio Galaxies and their contribution to the Isotropic Gamma-Ray Background
A. Circiello, A. McDaniel, M. Di Mauro +6
We evaluate the contribution to the Isotropic Gamma-Ray Background (IGRB) coming from Radio Galaxies (RGs), the subclass of radio-loud Active Galactic Nuclei (AGN) with the highest…
New determination of the neutrino hadronic production cross sections from GeV to beyond PeV energies
Luca Orusa, Mattia Di Mauro, Fiorenza Donato
The flux of astrophysical neutrinos is now measured with unprecedented accuracy and over several decades of energy spectrum. Their origin traces back to hadronic collisions between…
Antinuclei from Primordial Black Holes
Valentina De Romeri, Fiorenza Donato, David Maurin +2
Light primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe. Their Hawking evaporation into particles cou…
Multiwavelength observation of a candidate pulsar halo LHAASO J0621+3755 and the first X-ray detection of PSR J0622+3749
C. B. Adams, A. Archer, P. Bangale +71
Pulsar halos are regions around middle-aged pulsars extending out to tens of parsecs. The large extent of the halos and well-defined central cosmic-ray accelerators make this new c…
Disclosing the catalog pulsars dominating the Galactic positron flux
Luca Orusa, Silvia Manconi, Fiorenza Donato +1
The cosmic-ray flux of positrons is measured with high precision by the space-borne particle spectrometer AMS-02. The hypothesis that pulsars and their nebulae can significantly co…
Geminga's pulsar halo: an X-ray view
Silvia Manconi, Jooyun Woo, Ruo-Yu Shang +6
Geminga is the first pulsar around which a remarkable TeV gamma-ray halo extending over a few degrees was discovered by MILAGRO, HAWC and later by H.E.S.S., and by Fermi-LAT in the…
The Galactic center excess at the highest energies: morphology and photon-count statistics
Silvia Manconi, Francesca Calore, Fiorenza Donato
The nature of the GeV gamma-ray Galactic center excess (GCE) in the data of Fermi-Large Area Telescope (LAT) is still to be unveiled. We present a new analysis of the inner Galaxy…
Dissecting the inner Galaxy with -ray pixel count statistics
Francesca Calore, Fiorenza Donato, Silvia Manconi
We combine adaptive template fitting and pixel count statistics in order to assess the nature of the Galactic center excess in Fermi-LAT data. We reconstruct the flux distribution…
Theoretical interpretation of Pass 8 Fermi-LAT data
Mattia Di Mauro, Silvia Manconi, Andrea Vittino +12
The flux of positrons and electrons () has been measured by the Large Area Telescope (LAT) in the energy range between 7 GeV and 2 TeV. We discuss a number of in…
Anisotropies in GeV-TeV cosmic ray electrons and positrons
Silvia Manconi, Mattia Di Mauro, Fiorenza Donato
High energy cosmic ray electrons and positrons probe the local properties of our Galaxy. In fact, electromagnetic energy losses limit the typical propagation scale of GeV-TeV elect…
Conservative upper limits on WIMP annihilation cross section from Fermi-LAT -rays
F. Donato, F. Calore, V. De Romeri
The spectrum of an isotropic extragalactic -ray background (EGB) has been measured by the Fermi-LAT telescope at high latitudes. Two new models for the EGB are derived from the…
