Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge
A. Acharyya, F. Aharonian, H. Ashkar +130
Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…

Multi-GeV Fermi-LAT Detection of PSR B1259-63
D. Malyshev, M. Chernyakova, A. Finn Gallagher +5
PSR B1259-63/LS 2883 is a classical gamma-ray binary detected from radio to TeV energies near periastron. Using over 17 years of Fermi-LAT observations, we report the first signifi…

Multiwavelength coverage of the 2024 periastron passage of PSR B1259-63 / LS 2883
M. Chernyakova, D. Malyshev, B. van Soelen +9
PSR B1259-63 is a gamma-ray binary system with a 48 ms radio pulsar orbiting around an O9.5Ve star, LS 2883, in a highly eccentric ~3.4 yr long orbit. Close to the periastron the s…
