Lepto-hadronic modeling of blazars associated with well-reconstructed high-energy neutrino events
Leonard Pfeiffer, Margot Boughelilba, Simone Garrappa +3
The association of active galactic nuclei (AGN) with high-energy neutrinos has been studied through population and individual source analyzes, but whether these associations reflec…
Morphology-aware periodicity searches in Fermi-LAT blazars
Aaron A. Maldonado, Alberto Domínguez, Adithiya Dinesh +4
Standard periodicity searches in active galactic nuclei assume sinusoidal modulation, whereas gamma-ray blazar emission often features asymmetric flares and localized bursts. We in…
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…
Coincidence of a high-fluence blazar outburst with a PeV-energy neutrino event
M. Kadler, F. Krauß, K. Mannheim +40
The discovery of extraterrestrial very-high-energy neutrinos by the IceCube collaboration has launched a quest for the identification of their astrophysical sources. Gamma-ray blaz…
Unusual Flaring Activity in the Blazar PKS 1424-418 during 2008-2011
S. Buson, F. Longo, S. Larsson +24
Context. Blazars are a subset of active galactic nuclei (AGN) with jets that are oriented along our line of sight. Variability and spectral energy distribution (SED) studies are cr…
