Self-regulating AGN jets in MHD simulations of cool-core clusters yield realistic FRI radio morphologies viewed along the jet axis and account for frequency-independent lobe extents via 1-50 μG fields allowing both young and old electrons to radiate.
Advection-only galactic wind models fail to reproduce observed vertical radio profiles without unrealistic velocities, synchrotron spectra are biased toward young electrons in dense regions, and bremsstrahlung/Coulomb losses cannot be neglected even when subdominant.
Multi-wavelength MCMC modeling of RCW 38 supports hadronic gamma-ray production with K_ep ≲ 10^{-3} and acceleration efficiency ≳1%, consistent with cosmic-ray composition requirements.
The radio/infrared/gamma-ray correlation in star-forming galaxies emerges from geometric projection through a radially structured disc, not from local cosmic-ray calorimetry.
Multiphase ISM simulations show PeV cosmic-ray diffusion coefficients reach 10^30 cm^2 s^-1, with perpendicular transport boosted at thermal phase boundaries while overall transport is controlled by trans-Alfvenic warm and unstable gas.
Oblique shocks in massive star clusters accelerate cosmic rays to multi-PeV energies, reproducing the LHAASO-observed knee as a sequence of rigidity-dependent cutoffs from combined supernova and wind shocks.
Galactic cosmic rays in a giant CGM halo develop an extended 1/r spatial tail and broader age distribution while remaining consistent with secondary-to-primary ratio data.
A review summarizing pitfalls in older CR-MHD models and progress toward more rigorous treatments that connect microphysical CR scales to galactic dynamics.
Review chapter summarizing the importance of small-scale galactic magnetic fields and proposing SKA observation strategies.

Simulating realistic radio morphologies of Fanaroff-Riley I jets in a self-regulating cool-core cluster
Self-regulating AGN jets in MHD simulations of cool-core clusters yield realistic FRI radio morphologies viewed along the jet axis and account for frequency-independent lobe extents via 1-50 μG fields allowing both young and old electrons to radiate.

Revisiting radio synchrotron diagnostics in star-forming galaxies
Advection-only galactic wind models fail to reproduce observed vertical radio profiles without unrealistic velocities, synchrotron spectra are biased toward young electrons in dense regions, and bremsstrahlung/Coulomb losses cannot be neglected even when subdominant.
