Road map for the tuning of hadronic interaction models with accelerator-based and astroparticle data Open
In high-energy and astroparticle physics, event generators play an essential role, even in the simplest data analyses. As analysis techniques become more sophisticated, e.g. based on deep neural networks, their correct description of the o…

Ultra-High-Energy Cosmic Rays from Neutrino-Emitting Tidal Disruption Events Open
We revisit the Ultra-High-Energy Cosmic Ray (UHECRs) production in Tidal Disruption Events (TDEs) in the light of recent neutrino-TDE associations. We use an isotropically emitting source-propagation model, which has been developed to desc…

Differences between the Pierre Auger Observatory and Telescope Array Spectra: Systematic Effects or Indication of a Local Source of Ultra-high-energy Cosmic Rays? Open
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) above 30 EeV. In this work we present a joint fit of TA and …

Differences between PAO and TA spectra: Systematics or indication of a local astrophysical source? Open
We present a joint fit of ultra-high-energy cosmic ray (UHECR) source scenarios to data from the Telescope Array (TA) and Pierre Auger Observatory (PAO) experiments [arXiv:2208.12274]. Our simulations account for the propagation of UHECRs …

Spectral softening in core-collapse supernova remnant expanding inside wind-blown bubble Open
Context. Galactic cosmic rays (CRs) are widely assumed to arise from diffusive shock acceleration, specifically at shocks in supernova remnants (SNRs). These shocks expand in a complex environment, particularly in the core-collapse scenari…

Leptonic Nonthermal Emission from Supernova Remnants Evolving in the Circumstellar Magnetic Field Open
The very-high-energy (VHE; E > 100 GeV) gamma-ray emission observed from a number of supernova remnants (SNRs) indicates particle acceleration to high energies at the shock of the remnants and a potentially significant contribution to Gala…

Particle acceleration in supernova remnant expanding inside wind-blown bubble Open
CONTEXT: Supernova Remnants (SNRs) are considered as the primary sources of galactic cosmic rays (CRs), where CRs are assumed to be accelerated by diffusive shock acceleration (DSA) mechanism. The SNR shocks expand in the complex ambient e…

Production of secondary particles in heavy nuclei interactions in supernova remnants Open
Depending on their type, supernova remnants may have ejecta material with high abundance of heavy elements such as carbon or oxygen. In addition, core-collapse supernovae explode in the wind material of their progenitor star that may also …

Vela supernova remnant and its pulsar wind nedula: physical characteristics and radio emission Open
Vela Supernova remnant (SNR) is one of the nearest SNRs to Earth and serves as a space laboratory of relativistic and pulsar astrophysics. In particular, its synchrotron radio emission is determined by physical processes both in the remnan…
