An Accretion Flare Interpretation for the Ultra-High-Energy Neutrino Event KM3-230213A
Chengchao Yuan, Leonard Pfeiffer, Walter Winter +4
We study the origin of the ultra-high-energy (UHE) neutrino event KM3-230213A detected by KM3NeT, focusing on MRC 0614-083 which has been pinpointed as the closest blazar to the ne…
The changing look of the neutrino-emitter blazar candidate 5BZQ J1243+4043
Alessandra Azzollini, Sara Buson, Alexis Coleiro
In recent years, changing-look blazars have called the traditional view of BL Lacs-flat spectrum radio quasars into question within the empirical classification of blazars. Based o…
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…
The physical properties of candidate neutrino-emitter blazars
Alessandra Azzollini, Sara Buson, Alexis Coleiro +5
The processes governing the production of astrophysical high-energy neutrinos are still debated, and the sources originating them remain an open question. Among the putative emitte…
X-ray Spectral Variability as Probe of Multimessenger Emission in Blazar 5BZB J0630-24064
Jose Maria Sanchez Zaballa, Sara Buson, Stefano Marchesi +4
X-ray observations are essential for understanding the multimessenger emission mechanisms of active galactic nuclei (AGN). Blazars, a subset of AGN whose X-ray emission predominant…
