The XRISM telescope discovered that the wind from neutron star GX 13+1 is not fast but exceptionally dense and slow. This changes our understanding of how such outflows are born and their impact on galaxies.

Years of observations with XMM-Newton, Swift, and VLA showed how the changing-look active galaxy 1ES 1927+654 underwent a dramatic transition from a wind regime to a jet. X-ray spectra revealed oxygen emission lines and a broad iron line, while ionized absorption faded. Synchronously, radio emission
