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…

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…

A Systematic Search for Spectral Hardening in Blazar Flares with the Fermi-Large Area Telescope

Adithiya Dinesh, Alberto Dominguez, V. Paliya +3

Blazars are a subclass of active galactic nuclei (AGN) that emit non-thermal radiation through relativistic jets, characterized by rapid flux and polarization variability. High syn…

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…

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…

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…
