First radio observations of SN 2023fyq detect a dense circumstellar shell with mass-loss rate ~0.004 solar masses per year ejected 0.7-3 years before explosion, consistent with a merger origin.

Radio and X-ray data on four old Type IIn supernovae show mass-loss rates 1-2 orders of magnitude below optical estimates, indicating rapidly evolving progenitor winds over the final centuries before explosion.
First IXPE polarization measurement of GX 340+0 in normal branch yields PD 1.22±0.25% and PA 38±6°, consistent with origin in blackbody or Comptonized emission, with radio flux lower than in horizontal branch.
Spatially resolved HI survey of eight Seyfert galaxies shows AGN feedback has limited impact on global atomic gas disk structure but may enhance local turbulence.
A faint radio counterpart to SN 2025ulz was detected at 6-10 GHz, consistent with either supernova ejecta interacting with circumstellar material or an off-axis jet, supporting possible superkilonova scenarios.
