Self-consistent modeling of energy-dependent synchrotron polarization in blazars with application to Mrk 421
Frederike Apel, Motseothata Tisang, Victor Barbosa Martins +3
Observations of black hole jets closely aligned with our line of sight, known as blazars, have revealed that their X-ray emission can be significantly more polarized than in the op…
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…
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…
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…
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…
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 energy…
The Spectra of IceCube Neutrino (SIN) candidate sources -- V. Modeling and interpretation of multiwavelength and neutrino data
Xavier Rodrigues, Martina Karl, Paolo Padovani +5
A correlation has been reported between the arrival directions of high-energy IceCube events and gamma-ray blazars classified as intermediate- and high-synchrotron-peaked BL Lacs.…
AM: An Open-Source Tool for Time-Dependent Lepto-Hadronic Modeling of Astrophysical Sources
Marc Klinger, Annika Rudolph, Xavier Rodrigues +6
We present the AM ("Astrophysical Multi-Messenger Modeling") software. AM is a documented open source software that efficiently solves the coupled integro-differential equa…
On the possible jet contribution to the -ray luminosity in NGC 1068
S. Salvatore, B. Eichmann, X. Rodrigues +2
NGC 1068 is a nearby widely studied Seyfert II galaxy presenting radio, infrared, X- and -ray emission as well as strong evidence for high-energy neutrino emission. Recently, th…
Leptohadronic Multimessenger Modeling of 324 Gamma-Ray Blazars
Xavier Rodrigues, Vaidehi S. Paliya, Simone Garrappa +3
The origin of the diffuse astrophysical neutrino flux observed by the IceCube experiment is still under debate. In recent years there have been associations of neutrino events with…
Differences Between the Pierre Auger Observatory and Telescope Array Spectra: Systematic Effects or Indication of a Local Source of Ultra-High-Energy Cosmic Rays?
Pavlo Plotko, Arjen van Vliet, Xavier Rodrigues +1
The Pierre Auger Observatory (PAO) and Telescope Array (TA) collaborations report significant differences in the observed energy spectra of ultra-high-energy cosmic rays (UHECRs) a…
The Blazar Hadronic Code Comparison Project
Matteo Cerruti, Michael Kreter, Maria Petropoulou +15
Blazar hadronic models have been developed in the past decades as an alternative to leptonic ones. In hadronic models the gamma-ray emission is associated with synchrotron emission…

The detection of the first electromagnetic counterpart to the binary neutron star (BNS) merger remnant GW170817 established the connection between short -ray bursts and BNS merg…
AGN jets as the origin of UHECRs and perspectives for the detection of astrophysical source neutrinos at EeV energies
Xavier Rodrigues, Jonas Heinze, Andrea Palladino +2
We demonstrate that a population of Active Galactic Nuclei (AGN) can describe the observed spectrum of ultra-high-energy cosmic rays (UHECRs) at and above the ankle, and that the d…
