A Radio-quiet AGN as a candidate counterpart to neutrino event IceCube-200615A
F. McBride, N. Schettino, J. D. O'Brien +13
Follow-up observations of neutrino events have been a promising method for identifying sources of very-high-energy cosmic rays. Neutrinos are unambiguous tracers of hadronic intera…

Search for the multiwavelength counterparts to extragalactic unassociated Fermi γ-ray sources
Alberto Ulgiati, Simona Paiano, Fabio Pintore +7
Aims. In this paper, we searched for multi-wavelength (X-ray, optical and radio) counterparts to the unassociated gamma-ray sources (UGS) of the Fermi 4FGL-DR4 catalog. The main go…

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…
