Dwarf Active Galactic Nuclei from Variability for the Origins of Seeds (DAVOS): Properties of Variability-Selected AGNs in the Dark Energy Survey Deep Fields

Yichen Liu, Colin J. Burke, Diego Miura +4

We study the black hole mass $-$ host galaxy stellar mass relation, $M_{BH} - M_{*}$ , for a sample of 706 $z ≲ 1.5$ and $i ≲ 24$ optically-variable active galac…

DAVOS: Dwarf Active Galactic Nuclei from Variability for the Origins of Seeds: Properties of Variability-Selected Active Galactic Nuclei in the COSMOS Field and Expectations for the Rubin Observatory

Colin J. Burke, Yichen Liu, Charlotte A. Ward +3

We study the black hole mass $-$ host galaxy stellar mass relation, $M_{BH} - M_{*}$ , of a sample of $z < 4$ optically-variable AGNs in the COSMOS field. The parent sample of 4…
