arkRayNet: Emulation of cosmic-ray antideuteron fluxes from dark matter
Jan Heisig, Michael Korsmeier, Michael Krämer +2
Cosmic-ray antimatter, particularly low-energy antideuterons, serves as a sensitive probe of dark matter annihilating in our Galaxy. We study this smoking-gun signature and explore…
Data-Driven Constraints on Cosmic-Ray Diffusion: Probing Self-Generated Turbulence in the Milky Way

We employ a data-driven approach to investigate the rigidity and spatial dependence of the diffusion of cosmic rays in the turbulent magnetic field of the Milky Way. Our analysis c…
Limits on dark matter annihilation in prompt cusps from the isotropic gamma-ray background
M. Sten Delos, Michael Korsmeier, Axel Widmark +3
Recent studies indicate that thermally produced dark matter will form highly concentrated, low-mass cusps in the early universe that often survive until the present. While these cu…
The self-confinement of electrons and positrons from dark matter
Marco Regis, Michael Korsmeier, Gianni Bernardi +3
Radiative emissions from electrons and positrons generated by dark matter (DM) annihilation or decay are one of the most investigated signals in indirect searches of WIMPs. Ideal t…
A novel prediction for secondary positrons and electrons in the Galaxy
Mattia Di Mauro, Fiorenza Donato, Michael Korsmeier +2
The Galactic flux of cosmic-ray (CR) positrons in the GeV to TeV energy range is very likely due to different Galactic components. One of these is the inelastic scattering of CR nu…
Fast and accurate AMS-02 antiproton likelihoods for global dark matter fits
