Particle Acceleration in Magnetized Shear-Driven Turbulence
Mingxuan Liu, Mateusz Ruszkowski, Ellen Zweibel +5
Shear flows, ubiquitous in space and astrophysical plasmas, can accelerate particles through turbulence excited by the Kelvin-Helmholtz instability. We present the first numerical…

The Impact of Cosmic Ray Transport on the -Ray Luminosity of Diffuse Gas
Roark Habegger, Mateusz Ruszkowski, Ellen G. Zweibel
Observations of -rays from diffuse gas provide the opportunity to study the distribution of high energy particles in different astrophysical environments. In the circumgalactic…

Cosmic ray transport and acceleration in an evolving shock landscape
Sophie Aerdker, Roark Habegger, Lukas Merten +2
The sources of cosmic rays between the knee and the ankle are still debated. The Galactic wind and its termination shock have been proposed to contribute to this transition between…
