Evidence for Supermassive Black Hole Binaries
Martin G. H. Krause, Martin A. Bourne, Silke Britzen +10
We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy…
Central Massive Black Holes Are Not Ubiquitous in Local Low-Mass Galaxies
Fan Zou, Elena Gallo, Anil C. Seth +13
The black-hole occupation fraction () defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity leve…
Magellan Spectroscopy of AGNs in Low-mass Galaxies: Scaling Relations and a Triple-Peaked AGN
Megan R. Sturm, Amy E. Reines, Jenny Greene +1
In this work, we aim to further populate the low-mass regime of black hole (BH) scaling relations to better understand the formation and growth mechanisms of central supermassive B…
The Morphology of Dwarf Galaxies Hosting Variable Active Galactic Nuclei
Erin Kimbro, Vivienne Baldassare, Guy Worthey +2
We analyze Hubble Space Telescope (HST) optical imaging of eight low-mass galaxies hosting active galactic nuclei (AGN) identified via their photometric variability in \cite{baldas…
