    Distinguishing Active Galactic Nuclei Feedback Models with the Thermal Sunyaev–Zel’dovich Effect by Skylar Grayson, Evan Scannapieco, Romeel Davé

    Published 2023-01-01
    “…Current models of galaxy formation require strong feedback from active galactic nuclei (AGN) to explain the observed lack of star formation in massive galaxies since z ≈ 2, but direct evidence of this energy input is limited. …”

    Reverberation mapping of active galactic nuclei: From X-ray corona to dusty torus by Edward M. Cackett, Misty C. Bentz, Erin Kara

    Published 2021-06-01
    “…Summary: The central engines of active galactic nuclei (AGNs) are powered by accreting supermassive black holes, and while AGNs are known to play an important role in galaxy evolution, the key physical processes occur on scales that are too small to be resolved spatially (aside from a few exceptional cases). …”

    IDENTIFYING LUMINOUS ACTIVE GALACTIC NUCLEI IN DEEP SURVEYS: REVISED IRAC SELECTION CRITERIA by Donley, J. L., Koekemoer, A. M., Brusa, M., Capak, P., Civano, F., Ilbert, O., Impey, C. D., Kartaltepe, J. S., Miyaji, T., Salvato, M., Sanders, D. B., Trump, J. R., Zamorani, G., Cardamone, Carolin

    Published 2015
    “…Spitzer/IRAC selection is a powerful tool for identifying luminous active galactic nuclei (AGNs). For deep IRAC data, however, the AGN selection wedges currently in use are heavily contaminated by star-forming galaxies, especially at high redshift. …”

    THE GLOBAL IMPLICATIONS OF THE HARD X-RAY EXCESS IN TYPE 1 ACTIVE GALACTIC NUCLEI by Tatum, M, Turner, T, Miller, L, Reeves, J

    Published 2013
    “…Recent evidence for a strong "hard excess" of flux at energies ≳ 20 keV in some Suzaku observations of type 1 active galactic nuclei (AGNs) has motivated an exploratory study of the phenomenon in the local type 1 AGN population. …”

    DIRECT MEASUREMENT OF THE X-RAY TIME-DELAY TRANSFER FUNCTION IN ACTIVE GALACTIC NUCLEI by Legg, E, Miller, L, Turner, T, Giustini, M, Reeves, J, Kraemer, S

    Published 2012
    “…The origin of the observed time lags, in nearby active galactic nuclei (AGNs), between hard and soft X-ray photons is investigated using new XMM-Newton data for the narrow-line SeyfertI galaxy Ark 564 and existing data for 1H0707-495 and NGC4051. …”

    Cosmic evolution of stellar-mass black hole merger rate in active galactic nuclei by Yang, Y, Bartos, I, Haiman, Z, Kocsis, B, Marka, S, Tagawa, H

    Published 2020
    “…Here we compute the cosmic evolution of the merger rate for stellar-mass binaries in the disks of active galactic nuclei (AGNs). We focus on recent evolution out to redshift z = 2, covering the accessible range of current Earth-based gravitational-wave observatories. …”
