    On the relative importance of hadronic emission processes along the jet axis of Active Galactic Nuclei by Hoerbe, MR, Morris, P, Cotter, G, Becker Tjus, J

    Published 2020
    “…With the coincident detection of a gamma-ray flare and a neutrino from the blazar TXS 0506+056, active galactic nuclei (AGNs) have been put into focus as possible sources of the diffuse neutrino flux. …”

    High-energy Neutrino Emission from Espresso-reaccelerated Ions in Jets of Active Galactic Nuclei by Rostom Mbarek, Damiano Caprioli, Kohta Murase

    Published 2023-01-01
    “…We present a bottom-up calculation of the flux of ultrahigh-energy cosmic rays (UHECRs) and high-energy neutrinos produced by powerful jets of active galactic nuclei (AGNs). By propagating test particles in 3D relativistic magnetohydrodynamic jet simulations, including a Monte Carlo treatment of sub-grid pitch-angle scattering and attenuation losses due to realistic photon fields, we study the spectrum and composition of the accelerated UHECRs and estimate the amount of neutrinos produced in such sources. …”

    Quiescent and Active Galactic Nuclei as Factories of Merging Compact Objects in the Era of Gravitational Wave Astronomy by Manuel Arca Sedda, Smadar Naoz, Bence Kocsis

    Published 2023-03-01
    “…Here, we review from a theoretical standpoint how different mechanisms concur with the formation, evolution, and merger of COBs around quiescent SMBHs and active galactic nuclei (AGNs), summarising the main predictions for current and future (GW) detections and outlining the possible features that can clearly mark a galactic nuclei origin.…”

    Fast Outflows and Luminous He ii Emission in Dwarf Galaxies with Active Galactic Nuclei (AGN) by Weizhe Liu, Sylvain Veilleux, Gabriela Canalizo, Todd M. Tripp, David S. N. Rupke, Archana Aravindan, Thomas Bohn, Fred Hamann, Christina M. Manzano-King

    Published 2024-01-01
    “…While stellar processes are believed to be the main source of feedback in dwarf galaxies, the accumulating discoveries of active galactic nuclei (AGN) in dwarf galaxies over recent years arouse the interest to also consider AGN feedback in them. …”
