    Hooks, Lines, and Sinkers: How Active Galactic Nucleus Feedback and Cosmic-Ray Transport Shape the Far-infrared–Radio Correlation of Galaxies by Sam B. Ponnada, Rachel K. Cochrane, Philip F. Hopkins, Iryna S. Butsky, Sarah Wellons, N. Nicole Sanchez, Cameron Hummels, Yue Samuel Lu, Dušan Kereš, Christopher C. Hayward

    Published 2025-01-01
    “…We present the first reproduction of the z  ∼ 0 FRC using detailed synthetic observations of state-of-the-art cosmological zoom-in simulations from the Feedback in Realistic Environments (FIRE-3) suite with explicitly evolved CR proton and electron (CRe) spectra, for three models for CR transport and multichannel active galactic nucleus (AGN) feedback. In doing so, we generally verify the predictions of “calorimeter” theories at high FIR luminosities ( L _60 _μ _m  ≳ 10 ^9.5 L _⊙ ) and at low FIR luminosities ( L _60 _μ _m ≲ 10 ^9.5 L _⊙ ), the so-called “conspiracy” of increasing UV radiation escape in tandem with increasing CRe escape, and find that the global FRC is insensitive to orders-of-magnitude locally variable CR transport coefficients. …”

    Evidence for AGN Feedback in Galaxy Clusters and Groups by Myriam Gitti, Fabrizio Brighenti, Brian R. McNamara

    Published 2012-01-01
    “…Instead of the initial idea that the thermal gas is cooling and flowing toward the center, the new picture envisages a complex dynamical evolution of the intracluster medium (ICM) regulated by the radiative cooling and the nongravitational heating from the active galactic nucleus (AGN). Understanding the physics of the hot gas and its interplay with the relativistic plasma ejected by the AGN is key for understanding the growth and evolution of galaxies and their central black holes, the history of star formation, and the formation of large-scale structures. …”

    An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN RE J1034+396 by Chloe S. Taylor, Daniel R. Wilkins, Steven W. Allen

    Published 2025-01-01
    “…We report the analysis of ∼1 Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus RE J1034+396. The 0.3–9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by relativistically blurred reflection from a highly ionized accretion disk. …”

    A Dichotomy in the 1–24 GHz Parsec-scale Radio Spectra of Radio-quiet Quasars by Sina Chen, Ari Laor, Ehud Behar, Ranieri D. Baldi, Joseph D. Gelfand, Amy E. Kimball

    Published 2025-01-01
    “…The steep 8.4–23.6 GHz slope sources may be produced by an interaction of an active-galactic-nucleus-driven wind with the BLR gas or a low-power jet extending to the BLR scale. …”
