An MHD-informed model with self-consistent radial profiles applied to ten z >= 2.5 quasar jets yields higher jet powers than one-zone models, favors electron distributions tied to gas pressure, and finds low magnetization with no clear redshift trend in Lorentz factor.

Multimessenger observations and one-zone leptohadronic modeling of PKS 1725+123 during a flare constrain its emission to external Compton gamma-rays, SSC X-rays, and a neutrino rate of about 0.3 events per year peaking at 1 PeV.
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.
3D RMHD simulations with hybrid particle tracking reproduce the weak radio and strong X-ray redshift evolution in AGN jets via IC/CMB, including the (1+z)^4 X-ray scaling and the alpha-z relation.
Ancient cosmic ray halos from the central galaxy boost Perseus's cool core via inverse-Compton scattering, simultaneously explaining radio minihalo, giant halo, X-ray properties, and gamma-ray data without re-acceleration.
GMRT sub-GHz survey of 44 magnetic hot stars detects emission in 11 cases and finds scaling of radio luminosity with magnetic field and rotation period consistent with higher-frequency work.
A dynamical model of magnetar-driven jet and PWN emission predicts a sequence of thermal, X-ray plateau, and late synchrotron/inverse-Compton radiation that accounts for key features in merger GRBs.
The January 2010 flare of Mrk421 shows spectral variability consistent with stochastic acceleration, including development of a Maxwellian pile-up component in the particle distribution on three nights.
Stacked blazar data show strongest gamma-ray to radio correlation at a 180-day delay, with some sources displaying 1-3 year lags between activity in the two bands.
Multi-telescope spectral modeling of HESS J1825-137 using Naima and MCMC shows leptonic dominance for existing GeV-TeV data but lepto-hadronic preference when adding simulated CTAO or LHAASO UHE points.
Calibrated AGN disk-wind models contribute ≲5% to the CGB above 10 GeV and ≲10% to the CNB at 100 TeV and are unlikely to dominate either background.
Overview of synergies between SKA radio observations and gamma-ray facilities for studying transient, variable, and steady GeV-TeV sources.
Review assessing HSP BL Lacs as UHECR and neutrino sources, noting strains from baryonic loading, heavy-nuclei preference in Auger data, and isotropy mismatch with beamed sources.
