Cosmic Pairs: A DESI Census of Dual and Offset AGN as Precursors to Massive Black Hole Binaries
Ekaterine Dadiani, Antonella Palmese, Yihao Zhou +52
The paper presents a large, uniformly selected spectroscopic catalog of dual and offset active galactic nuclei from the first DESI data release, analyzing their host galaxy propert…

Connecting current and future dual AGN searches to LISA and PTA gravitational wave detections
Nianyi Chen, Yihao Zhou, Ekaterine Dadiani +10
Dual active galactic nuclei (DAGN) mark an observable stage of massive black hole (MBH) pairing in galaxy mergers and are precursors to the MBH binaries that generate low-frequency…

z~2 dual AGN host galaxies are disky: stellar kinematics in the ASTRID Simulation
Ekaterine Dadiani, Tiziana Di Matteo, Nianyi Chen +6
We study dual AGN host galaxy morphologies at using the ASTRID simulation, selecting black hole (BH) pairs with small separation (), high mass ($M_{\text{BH,1…
