Importance of the Resonant Cosmic-Ray Streaming Instability Upstream of Collisionless Shocks
Bricker Ostler, Benedikt Schroer, Damiano Caprioli
Cosmic rays (CRs) escaping collisionless shocks form a dilute, relativistic population whose current amplifies the upstream magnetic field, a process widely attributed to the non-r…
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…
The role of non-linear Landau damping for cosmic-ray transport
Benedikt Schroer, Damiano Caprioli, Pasquale Blasi
We present the first assessment, using hybrid PIC simulations, of the role of non-linear Landau damping in the process of self-generated scattering in a high plasma, conditions…
The saturation of the Bell instability and its implications for cosmic ray acceleration and transport
D. Caprioli, G. Zacharegkas, C. Haggerty +2
The non-resonant (Bell) streaming instability driven by energetic particles is crucial for producing amplified magnetic fields that are key to the acceleration of cosmic rays (CRs)…
TeV halos and the role of pulsar wind nebulae as sources of cosmic ray positrons
Benedikt Schroer, Carmelo Evoli, Pasquale Blasi
The recent detection of the Geminga PWN by HAWC in the multi-TeV band allows us to infer precious information about the transport of pairs in the immediate surroundings of the puls…
Modeling the Saturation of the Bell Instability using Hybrid Simulations
Georgios Zacharegkas, Damiano Caprioli, Colby Haggerty +2
The nonresonant streaming instability (Bell instability) plays a pivotal role in the acceleration and confinement of cosmic rays (CRs); yet, the exact mechanism responsible for its…
Cosmic-ray generated bubbles around their sources
Benedikt Schroer, Oreste Pezzi, Damiano Caprioli +2
Cosmic rays are thought to escape their sources streaming along the local magnetic field lines. We show that this phenomenon generally leads to the excitation of both resonant and…
Intermediate mass and heavy Galactic cosmic-ray nuclei: the case of new AMS-02 measurements
Benedikt Schroer, Carmelo Evoli, Pasquale Blasi
The recent measurement of the spectra of intermediate mass nuclei and iron nuclei carried out with the AMS-02 experiment provided us with the most complete set of data on cosmic ra…
Dynamical Effects of Cosmic Rays on the Medium Surrounding Their Sources
Benedikt Schroer, Oreste Pezzi, Damiano Caprioli +2
Cosmic rays (CRs) leave their sources mainly along the local magnetic field; in doing so they excite both resonant and nonresonant modes through streaming instabilities. The excita…
Modeling the Saturation of the Bell Instability Using Hybrid Simulations
Georgios Zacharegkas, Damiano Caprioli, Colby Haggerty
The nonresonant cosmic ray instability, predicted by Bell (2004), is thought to play an important role in the acceleration and confinement of cosmic rays (CRs) close to supernova r…
