    FRAMEx. IV. Mechanical Feedback from the Active Galactic Nucleus in NGC 3079 by Luis C. Fernandez, Nathan J. Secrest, Megan C. Johnson, Travis C. Fischer

    Published 2023-01-01
    “…Using the Very Long Baseline Array, we observed the active galactic nucleus (AGN) in NGC 3079 over a span of six months to test for variability in the two main parsec-scale radio components, A and B , which lie on either side of the AGN. …”

    Modeling the Spectral Energy Distribution of the Active Galactic Nucleus inside NGC 4395 by Hector Afonso G. Cruz, Andy D. Goulding, Jenny E. Greene

    Published 2023-01-01
    “…We study the broadband spectral energy distribution (SED) of the prototypical low-mass active galactic nucleus (AGN) in NGC 4395. We jointly model the optical through mid-IR SED with a combination of galaxy and AGN light, and find that on arcsecond scales the AGN dominates at most wavelengths. …”

    Active galactic nucleus torus models and the puzzling infrared spectrum of IRAS F10214+4724 by Efstathiou, A, Christopher, N, Verma, A, Siebenmorgen, R

    Published 2013
    “…We first present and discuss a grid of smooth active galactic nucleus (AGN) torus models computed with the method of Efstathiou and Rowan-Robinson and demonstrate that the combination of these models and the starburst models of Efstathiou and coworkers, while able to give an excellent fit to the average spectrum of Seyfert 2s and spectra of individual type 2 quasars measured by Spitzer, fails to match the spectral energy distribution of IRAS F10214+4724. …”

    Investigating the Star Formation Rates of Active Galactic Nucleus Hosts Relative to the Star-forming Main Sequence by Nathan Cristello, Fan Zou, W. N. Brandt, Chien-Ting J. Chen, Joel Leja, Qingling Ni, Guang Yang

    Published 2024-01-01
    “…Specifically, it is still unclear how the position of X-ray active galactic nucleus (AGN) host galaxies with respect to the star-forming main sequence (MS) may change with the X-ray luminosity ( L _X ) of the AGN or the stellar mass ( M _⋆ ) of the host galaxy. …”
