    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. …”
