The evolution of galaxies is connected to the growth of supermassive black holes in their centers. During the quasar phase, a huge luminosity is released as matter falls onto the black hole, and radiation-driven winds can transfer most of this energy back to the host galaxy. Over five different epochs, we detected the signatures of a nearly spherical stream of highly ionized gas in the broadband X-ray spectra of the luminous quasar PDS 456. This persistent wind is expelled at relativistic speeds from the inner accretion disk, and its wide aperture suggests an effective coupling with the ambient gas. The outflow's kinetic power larger than 10^46 ergs per second is enough to provide the feedback required by models of black hole and host galaxy co-evolution.

  1. Fe K$\alpha$ line from the Broad Line Region of PDS456 with XRISM/Resolve

    astro-ph.HE 2026-07 conditional novelty 7.0

    XRISM/Resolve reveals a narrow, blueshifted neutral Fe Kα line (EW ≈ 9 eV, v_out ≈ 2700 km/s) in quasar PDS 456, likely from the outer Broad Line Region at the high-luminosity end of the X-ray Baldwin effect.

  2. First detection of ultra-fast outflows in a quiescent galaxy

    astro-ph.GA 2026-07 conditional novelty 7.0

    First detection of an ultra-fast outflow (v≈0.07c) in a quiescent galaxy quenched ~9 Gyr ago, suggesting AGN winds can maintain quiescence independent of global star formation.

  3. Investigating black hole accretion and feedback self-regulation in Seyfert galaxies using the FIRE-3 cosmological hydrodynamic simulations

    astro-ph.GA 2026-06 unverdicted novelty 5.0

    FIRE-3 cosmological simulations of Seyfert galaxies produce episodic AGN feedback and gas clearing but no clear anti-correlation between nuclear gas concentration and AGN luminosity, highlighting timing mismatches wit...
