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.
pGMCA separation of Chandra data yields the first uncontaminated X-ray maps of Sgr A East, with spectral fits showing lower ionization age and higher electron density than prior reports.
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.
Higher-resolution MUSE data shows the optical torus in SNR E0102 as a multiphase cavity whose line ratios require coexisting shock and ionization conditions rather than any single-component model.
XSNAP provides a unified pipeline for X-ray supernova analysis and derives a progenitor mass-loss rate of (6.2±0.2)×10^{-5} solar masses per year for SN 2024ggi assuming a 20 km/s wind.
Radiative filaments in the Cygnus Loop exhibit thermal radio spectra resembling HII regions instead of typical SNR non-thermal emission.
Spectra of the western eROSITA bubbles reveal two uniform components at 0.60 keV and 0.21 keV with sub-solar abundances, plus a geometrical model constraining horizontal size to ~6 kpc but leaving vertical extent uncertain.
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.
Reconstruction of GRO J1655-40, SAX J1819.3-2525 and 4U 1543-47 requires CE efficiencies α_0.5U ≳6.7, α_U ≳4.2, α_H ≳1.7 with no solutions below unity, implying need for additional energy or formalism changes plus natal kicks ≳50 km/s for 4U 1543-47.
Extended gamma-ray emission around Berkeley 59 is produced by cosmic rays accelerated in cluster winds colliding with ambient gas.
