Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The authors re‑analyse Fermi‑LAT gamma‑ray data from the Galactic Center using adaptive template fitting and photon‑count statistics to separate a possible dark‑matter signal from…
Weakly supervised machine learning for model-agnostic searches of new phenomena in the -ray sky
Michael Krämer, Silvia Manconi, Kathrin Nippel
The -ray sky, as observed by the Fermi Large Area Telescope, contains a significant number of unassociated sources that may point to new astrophysical populations or more exoti…
Cosmic-Ray Signatures of Annihilating and Semi-Annihilating Dark Matter via One-Step Cascades
Francesco D'Eramo, Silvia Manconi, Tommaso Sassi
We present a framework in which three classes of dark matter number-changing processes can affect both the relic abundance via thermal freeze-out in the early universe and the gene…
Search for TeV emission from spider millisecond pulsars with HAWC
R. Alfaro, E. Anita-Rangel, M. Araya +90
Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…
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…
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…
