The impact of the eROSITA bubbles on Galactic cosmic-ray transport
Benedikt Schroer
We propose that the observed spectral hardening in Galactic cosmic ray fluxes is governed by macroscopic Galactic outflows, such as the eROSITA bubbles, rather than microphysical v…
Investigating Nonlinear Landau Damping in Hybrid Simulations
Benedikt Schroer, Damiano Caprioli, Pasquale Blasi
Phenomenological studies of cosmic-ray self-confinement often hinge on the linear theory for the growth rate of the streaming instability and for the damping rate of the generated…
The Origin of the Very-High-Energy Diffuse -Ray Emission: The Case for Galactic Source Cocoons
Antonio Ambrosone, Carmelo Evoli, Benedikt Schroer +1
The secondary/primary cosmic-ray ratios and the diffuse backgrounds of gamma rays and neutrinos provide us with complementary information about the transport of Galactic cosmic ray…
A Critical Examination of the Nested Leaky Box Model for Galactic Cosmic Ray Transport
Benedikt Schroer, Carmelo Evoli, Pasquale Blasi
We revisit the predictions of the nested leaky box model in detail, in terms of both primary cosmic-ray spectra, spectra of stable and unstable nuclei and antimatter production (po…
Understanding Streaming Instabilities in the Limit of High Cosmic Ray Current Density
Emily Lichko, Damiano Caprioli, Benedikt Schroer +1
A critical component of particle acceleration in astrophysical shocks is the non-resonant (Bell) instability, where the streaming of cosmic rays (CRs) leads to the amplification of…
