    THE NUCLEAR INFRARED EMISSION OF LOW-LUMINOSITY ACTIVE GALACTIC NUCLEI by Mason, R, Lopez-Rodriguez, E, Packham, C, Alonso-Herrero, A, Levenson, N, Radomski, J, Ramos Almeida, C, Colina, L, Elitzur, M, Aretxaga, I, Roche, P, Oi, N

    Published 2012
    “…We present high-resolution mid-infrared (MIR) imaging, nuclear spectral energy distributions (SEDs), and archival Spitzer spectra for 22 low-luminosity active galactic nuclei (LLAGNs; L bol ≲ 10 42 erg s -1). Infrared (IR) observations may advance our understanding of the accretion flows in LLAGNs, the fate of the obscuring torus at low accretion rates, and, perhaps, the star formation histories of these objects. …”

    Past, Present, and Future of the Scaling Relations of Galaxies and Active Galactic Nuclei by Mauro D’Onofrio, Mauro D’Onofrio, Paola Marziani, Cesare Chiosi

    Published 2021-11-01
    “…We review the properties of the established Scaling Relations (SRs) of galaxies and active galactic nuclei (AGN), focusing on their origin and expected evolution back in time, providing a short history of the most important progresses obtained up to now and discussing the possible future studies. …”
