Hard X-ray Sources in Fermi UFOs
Alessandro Paggi, Ioannis Liodakis, John Antoniadis +7
Identification and/or association of unidentified -ray sources with lower-energy counterparts represents a key challenge in modern astronomy, due to the relatively large positio…
Association of the IceCube neutrinos with CAZ blazar light curves
Pouya M. Kouch, Talvikki Hovatta, Elina Lindfors +3
The IceCube Neutrino Observatory has detected several hundred high-energy neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not known…
CAZ catalog and optical light curves of 7918 blazar-selected active galactic nuclei
Pouya M. Kouch, Elina Lindfors, Talvikki Hovatta +10
Active galactic nuclei (AGN) are some of the brightest and most variable objects in the Universe. Those with relativistic jets observed at small viewing angles are blazars. Due to…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
Swift-XRT follow-up analysis of unidentified hard X-ray sources
M. Kosiba, F. Massaro, A. Paggi +5
It is currently established that the sources contributing to the cosmic X-ray background (CXB) emission are mainly nearby active galactic nuclei (AGN), in particular those that are…
Detection of X-ray Polarization from the Blazar 1ES 1959+650 with the Imaging X-ray Polarimetry Explorer
Manel Errando, Ioannis Liodakis, Alan P. Marscher +142
Observations of linear polarization in the 2-8 keV energy range with the Imaging X-ray Polarimetry Explorer (IXPE) explore the magnetic field geometry and dynamics of the regions g…
