Spurred by rich, multiwavelength observations and enabled by new simulations, ranging
from cosmological to subparsec scales, the past decade has seen major theoretical …

Understanding the physical mechanisms that control galaxy formation is a fundamental
challenge in contemporary astrophysics. Recent advances in the field of astrophysical …

The nature of cosmic ray (CR) transport in the Milky Way remains elusive. The predictions of
current microphysical CR transport models in magnetohydrodynamic (MHD) turbulence are …

Magnetic fields are crucial in numerous astrophysical processes within the interstellar
medium (ISM). However, the detailed determination of magnetic field geometry is notoriously …

Context. The details of cosmic-ray transport have a strong impact on galaxy evolution. The
peak of the cosmic-ray energy distribution is observable in the radio continuum using the …

In a weakly compressible high-β medium, pitch-angle scattering and the associated
scattering acceleration of cosmic rays (CRs) by anisotropic Alfvén and slow modes of …

We investigate how cosmic rays (CRs) affect thermal and hydrostatic stability of
circumgalactic (CGM) gas, in simulations with both CR streaming and diffusion. Local …

Context. Indirect observations of the cosmic-ray electron (CRE) distribution via synchrotron
emission is crucial for deepening the understanding of the CRE transport in the interstellar …

Cosmic rays in star-forming galaxies are a dominant source of both diffuse γ-ray emission
and ionization in gas too deeply shielded for photons to penetrate. Though the cosmic rays …

The coupling state between ions and neutrals in the interstellar medium plays a key role in
the dynamics of magnetohydrodynamic (MHD) turbulence, but is challenging to study …
