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…

Improved photomeson model for interactions of cosmic ray nuclei

Leonel Morejon, Anatoli Fedynitch, Denise Boncioli +2

Photon-hadronic interactions are important for the sources and the transport of Ultra-High Energy Cosmic Rays (UHECRs). Current state-of-the-art cosmic ray transport simulations ha…

Astrophysical neutrino production and impact of associated uncertainties in photo-hadronic interactions of UHECRs

Daniel Biehl, Denise Boncioli, Anatoli Fedynitch +2

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…

On the common origin of cosmic rays across the ankle and diffuse neutrinos at the highest energies from low-luminosity Gamma-Ray Bursts

Denise Boncioli, Daniel Biehl, Walter Winter

We demonstrate that the UHECRs produced in the nuclear cascade in the jet of Low-Luminosity Gamma-Ray Bursts (LL-GRBs) can describe the UHECR spectrum and composition and, at the s…

Binary Neutron Star Merger Remnants as Sources of Cosmic Rays Below the "Ankle"

Xavier Rodrigues, Daniel Biehl, Denise Boncioli +1

We investigate non-thermal electron and nuclei energy losses within the binary neutron star merger remnant produced by the event GW170817. The lack of a cooling feature within the…
