XRISM observation of 3C 111 finds weak Fe Kβ possibly caused by blueshifted absorption from an ionized wind at 4600 or 17200 km/s, with kinetic power 10^41-10^44 erg/s smaller than the jet power.
Multi-phase molecular gas in IRAS20551-4250 is dominated by cold CO, shows UV-heated warm H2, tidal features from a merger, and no molecular outflows, consistent with ongoing star formation.
Larger supermassive black holes drive greater atmospheric heating, mass loss, and near-total ozone depletion on exoplanets, with effects strongest in energy-driven winds and closer to the galactic center.
In X-ray selected AGN, those hosting ultra-fast outflows exhibit larger radio extensions and steep spectra matching wind-driven shock models.
A model of accretion-disk dynamos as synchronized macro-spins unifies broadband variability, coronal heating, jets, and hard/soft cycles via collective spin dynamics.
