UHECR from high- and low-luminosity Gamma-Ray Bursts Open
For a long time Gamma-Ray Bursts (GRBs) have been discussed as potential origin of Ultra-High-Energy Cosmic Rays (UHECRs). This paradigm is challenged by the lack of High-Energy (HE) neutrinos detected by IceCube that could be associated w…

Systematic parameter space study for the UHECR origin from GRBs in models with multiple internal shocks Open
We scrutinize the paradigm that conventional long-duration gamma-ray bursts (GRBs) are the dominant source of the ultrahigh energy cosmic rays (UHECRs) within the internal shock scenario by describing UHECR spectrum and composition and by …

Gamma-Ray Bursts as Sources of Ultra-High Energy Cosmic Rays across the Ankle Open
The origin of Ultra-High Energy Cosmic Rays (UHECRs) is still unknown. Gamma-Ray Bursts (GRBs) are considered as potential sources as they belong to the most energetic events observed to date. However, conventional GRB scenarios are strong…

On the Common Origin of Cosmic Rays across the Ankle and Diffuse Neutrinos at the Highest Energies from Low-luminosity Gamma-Ray Bursts Open
We demonstrate that the ultra-high-energy cosmic rays (UHECRs) produced in the nuclear cascade in the jets of low-luminosity gamma-ray bursts (LL-GRBs) can describe the UHECR spectrum and composition, and at the same time, the diffuse neut…

Astrophysical neutrino production and impact of associated uncertainties in photo-hadronic interactions of UHECRs Open
High energy neutrinos can be produced by interactions of ultra-high energy cosmic rays (UHECRs) in the dense radiation fields of their sources as well as off the cosmic backgrounds when they propagate through the universe. Multi-messenger …

Expected neutrino fluence from short Gamma-Ray Burst 170817A and off-axis angle constraints Open
We compute the expected neutrino fluence from SGRB 170817A, associated with the gravitational wave event GW 170817, directly based on Fermi observations in two scenarios: structured jet and off-axis (observed) top-hat jet. While the expect…

Cosmic ray and neutrino emission from gamma-ray bursts with a nuclear cascade Open
Aim. We discuss neutrino and cosmic ray emission from gamma-ray bursts (GRBs) with the injection of nuclei, where we take into account that a nuclear cascade from photodisintegration can fully develop in the source. Our main objective is t…

Exploring potential cosmic ray accelerators with neutrinos: what do we learn by injecting nuclei in Gamma-Ray Bursts? Open
Neutrino stacking analysis constrains the paradigm that Gamma-Ray Bursts (GRBs) are the sources of the Ultra-High Energy Cosmic Rays (UHECRs). However, most of the literature has focused on a pure proton composition of UHECRs, which has be…
