An Evolving Leptonic Jet Model for Delayed Radio Flares in Neutrino Blazars

Alina Kochocki, Xavier Rodrigues, Nathan Whitehorn

The jets of blazar active galactic nuclei (AGN) are promising sites of hadron acceleration and subsequent neutrino production, owing to their extreme intrinsic power and high radia…

Hillas meets Eddington: The case for blazars as ultra-high-energy neutrino sources

Xavier Rodrigues, Frank Rieger, Artem Bohdan +1

Blazars are promising high-energy neutrino source candidates. However, leptohadronic models face challenges in describing neutrino emission within a viable energy budget, and their…

Neutrinos from extreme astrophysical sources

Xavier Rodrigues

In this paper I review recent results on high-energy neutrino astronomy and what they can reveal about some of the most extreme cosmic accelerators. I discuss recent measurements o…

A Comprehensive Hadronic Code Comparison for Active Galactic Nuclei

Matteo Cerruti, Annika Rudolph, Maria Petropoulou +14

We perform the first dedicated comparison of five hadronic codes (AM, ATHEA, B13, LeHa-Paris, and LeHaMoC) that have been extensively used in modeling of the spectral energ…

Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020

MAGIC Collaboration, S. Abe, J. Abhir +228

The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…
