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.

JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
SED fitting of star clusters in NGC 628 identifies an evolutionary sequence from embedded young clusters to visible ones with a photo-dissociation region clearing timescale of approximately 4 Myr.
A radio-luminosity-based model of mild q decrease to z~2 from cosmic ray losses mitigates the >3σ discrepancy in MeerKAT source counts near 10 μJy with ≥2σ evidence, while bounding intrinsic scatter.
Simulations of evolving galaxies show strong L_nu-SFR and L_nu-V_rot correlations up to z~3, with turbulent magnetic fields dominating at low redshift and large-scale fields growing in importance at higher redshift.
Five new HI 21-cm absorption detections in LERGs and HERGs at z<0.5 reveal disturbed gas kinematics with velocity offsets over 350 km/s and a 3% detection rate consistent with lower-redshift samples.
VLBI observations resolve NGC 7479's nucleus into two radio components separated by ~30 mas with an apparent change in separation over a decade, suggesting relativistic jet motion or nuclear wind shocks.
Time-dependent cosmic ray electron spectra in a simulated galactic disk match steady-state solutions up to 500 GeV but become steeper and more disk-confined at higher energies due to recent injections.
MHD simulations indicate that SKA-Mid Band 5a can detect filamentary polarized emission from ICM magnetic fields at high resolution and sensitivity, allowing inference of turbulence driving scales.
Simulations of an SKA-Mid survey predict detection of 1.5e4 star-forming galaxies to z~7 with thermal SFR uncertainties of 0.1 dex, enabling constraints on cosmic star formation rate density.
Multi-scale radio observations of 15 local U/LIRGs decompose emission to show nuclear components contribute ~50% on average while diffuse SF-related emission dominates ~80% of total power, with radio excess linked to AGN rather than boosted star formation.
Simulations predict ngVLA at 100 GHz can detect galaxies above 10^9 solar masses at any redshift while SKA low frequencies reach massive dusty galaxies to z=5-7.
Forecasts angular clustering for a 20,000 sq deg SKAO radio continuum survey reaching O(300-400 million) sources and discusses needed corrections for telescope systematics and population modeling.
