    CHARACTERIZING THE OPTICAL VARIABILITY OF BRIGHT BLAZARS: VARIABILITY-BASED SELECTION OF FERMI ACTIVE GALACTIC NUCLEI by Ruan, John J., Anderson, Scott F., MacLeod, Chelsea L., Becker, Andrew C., Burnett, T. H., Davenport, James R. A., Kochanek, Christopher S., Plotkin, Richard M., Sesar, Branimir, Stuart, J. Scott, Ivezic, Zeljko

    Published 2015
    “…Despite the extreme stellar contamination at the shallow depth of the LINEAR survey, we are able to recover previously associated optical counterparts to Fermi active galactic nuclei with E ≥ 88% and C = 88% in Fermi 95% confidence error ellipses having semimajor axis r < 8'. …”

    Quiescent and active galactic nuclei as factories of merging compact objects in the era of gravitational wave astronomy by Sedda, MA, Naoz, S, Kocsis, B

    Published 2023
    “…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.…”
