Sgr A* as a Galactic PeVatron: Multimessenger Signatures of the Magnetic Penrose Process
Marina Cermeño, Pedro De la Torre Luque, Cristina Fernández-Suárez +5
The magnetic Penrose process (MPP) is one of the most efficient mechanisms for extracting rotational energy from a magnetized Kerr black hole (BH), enabling charged particles to re…
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…
Deeper analysis of Fermi-LAT unassociated 4FGL J2112.5-3043 for possible identification
Federica Giacchino, Cristina Fernández-Suárez, Miguel Á Sánchez-Conde +3
In the 4FGL-DR4 point-source catalog of the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Observatory (Fermi-LAT), around a third of the sources are still unidentified…
A Search for Dark Matter Annihilation in Stellar Streams with the Fermi-LAT
Cristina Fernandez-Suarez, Miguel A. Sanchez-Conde
Stellar streams are remnants of globular clusters or dwarf galaxies that have been tidally disrupted by the gravitational potential of their host galaxy. Streams originating from d…
