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…
Subphotospheric Emission from Short Gamma-Ray Bursts. II.~Signatures of Non-Thermal Dissipation in the Multi-Messenger Signals
Annika Rudolph, Irene Tamborra, Ore Gottlieb
Building on a general relativistic magnetohydrodynamic simulation of a short gamma-ray burst (sGRB) jet with initial magnetization , propagating through the dynamical ejec…
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…
Subphotospheric emission from short gamma-ray bursts: Protons mold the multi-messenger signals
Annika Rudolph, Irene Tamborra, Ore Gottlieb
The origin of the observed Band-like photon spectrum in short gamma-ray bursts (sGRBs) is a long-standing mystery. We carry out the first general relativistic magnetohydrodynamic s…
Probing gamma-ray bursts observed at very high energies through their afterglow
Ersilia Guarini, Irene Tamborra, Damien Bégué +1
A growing number of gamma-ray burst (GRB) afterglows is observed at very-high energies (VHE, GeV). Yet, our understanding of the mechanism powering the VHE emission r…
Multi-messenger model for the prompt emission from GRB 221009A
Annika Rudolph, Maria Petropoulou, Walter Winter +1
We present a multi-messenger model for the prompt emission from GRB 221009A within the internal shock scenario. We consider the time-dependent evolution of the outflow with its imp…
Multi-collision internal shock lepto-hadronic models for energetic GRBs
Annika Rudolph, Maria Petropoulou, Željka Bošnjak +1
For a sub-population of energetic Gamma-Ray Bursts (GRBs), a moderate baryonic loading may suffice to power Ultra-High-Energy Cosmic Rays (UHECRs). Motivated by this, we study the…
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…
Multi-wavelength radiation models for low-luminosity GRBs, and the implications for UHECRs
Annika Rudolph, Željka Bošnjak, Andrea Palladino +2
We study the prompt phase of low-luminosity Gamma-Ray Bursts (ll-GRBs) as potential source of very-high-energy (VHE) gamma rays and Ultra-High-Energy Cosmic Rays (UHECRs). Within t…
Systematic parameter space study for the UHECR origin from GRBs in models with multiple internal shocks
Jonas Heinze, Daniel Biehl, Anatoli Fedynitch +3
We scrutinize the paradigm that conventional long-duration Gamma-Ray Bursts (GRBs) are the dominant source of the ultra-high energy cosmic rays (UHECRs) within the internal shock s…
Impact of the collision model on the multi-messenger emission from Gamma-Ray Burst internal shocks
Annika Rudolph, Jonas Heinze, Anatoli Fedynitch +1
We discuss the production of multiple astrophysical messengers (neutrinos, cosmic rays, gamma-rays) in the Gamma-Ray Burst (GRB) internal shock scenario, focusing on the impact of…
