ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization

Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42

We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…

Dual AGN and Multiple SMBH Systems in the Era of SKAO

Q. D'Amato, L. Cui, R. Deane +23

We present a radio-oriented review of current strategies for the detection and characterization of dual active galactic nuclei (DAGN) and supermassive black hole binaries (SMBHBs),…

Ultraviolet diversity of Little Red Dots as a probe for direct-collapse black hole ages

Elia Cenci, Melanie Habouzit, Dale D. Kocevski

Little Red Dots (LRDs) uncovered by the James Webb Space Telescope have been proposed as candidate galaxies hosting embedded accreting direct-collapse black holes (DCBHs), yet the…

The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries

David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67

In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…

SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6

John Silverman, Junyao Li, Xuheng Ding +36

The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The Jame…

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…
