A Search for GeV Emission from Magnetar Giant Flare Candidates with Fermi-LAT

Vikas Chand, Michela Negro, Nicola Omodei +5

The discovery of delayed GeV emission from the extragalactic magnetar giant flare (MGF) GRB 200415A, located in the nearby Sculptor galaxy, revealed for the first time that these r…

Colour evolution in the radio afterglow of GRB 241025A

S. Giarratana, O. S. Salafia, L. Nava +10

We present the observing campaign of the afterglow of GRB241025A, a gamma-ray burst (GRB) whose prompt emission has been simultaneously detected by Swift, Einstein Probe, Fermi/GBM…

Kes 75 with IXPE: Detection of Nebular X-ray Polarization and Change in Pulsar Lightcurve

Josephine Wong, Jack T. Dinsmore, Roger W. Romani +16

We present the first X-ray polarization measurements of the PSR/PWN complex within SNR Kes 75. Two IXPE observations were conducted in October/November 2024 a…

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…

A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories

Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2

We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…

Constraints on axion-like particles from ultra-high-energy observations of M87 with the HAWC observatory

R. Alfaro, C. Alvarez, A. Andrés +95

In this work, we perform an indirect search for axion-like particles (ALPs) through their hypothesized mixing with photons in the presence of magnetic fields. ALPs are a well-motiv…
