CRPropa 3.3: Toward a Unified Multi-Messenger Framework from GeV to ZeV Energies

Sophie Aerdker, Rafael Alves Batista, Julia Becker Tjus +11

We present CRPropa 3.3, the latest release of the publicly available Monte Carlo framework for simulating the propagation of high-energy particles in astrophysical environments. Th…

Spectra for the Vacuum Cherenkov Effect in Astrophysical Electromagnetic Cascades with Lorentz Invariance Violation

Andrey Saveliev, Rafael Alves Batista, Feodor Mishin

Lorentz invariance violation is a feature of several quantum gravity models in which Lorentz symmetry is broken at high energies, possibly leading to changes in particle behavior a…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

Modeling of Dark Matter Prompt and Secondary Signatures in Dwarf Galaxies

Athithya Aravinthan, Julien Dörner, Julia Becker Tjus +6

Dwarf Spheroidal (dSph) galaxies are very promising laboratories for the indirect search for dark matter (DM), due to their low astrophysical background in radio and gamma-ray freq…

Testing the influence of anisotropic CR transport and the Galactic magnetic field structure on the all-sky gamma-ray emission

Julien Dörner, Jonas Hellrung, Julia Becker Tjus +1

The spatial diffusion of energetic particles in a magnetic field composed of a large-scale background and a small-scale turbulent component should be expected to be anisotropic. Wh…

Cosmic-ray propagation features in gamma-ray measurements

Julia Becker Tjus, Julien Dörner, Leander Schlegel +1

Gamma-ray measurements from GeV to PeV energies have provided us with a wealth of information on diffuse emission and sources in the Universe lately. With improved spatial and temp…
