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…
The Galaxy Luminosity Functions in ASTRID: Predictions for LSST
Fatemeh Hafezianzadeh, Tianqing Zhang, Paul Rogozenski +6
We present validated and forward-modelled galaxy luminosity functions and photometric predictions for the Vera C. Rubin Observatory Legacy Survey of Space and Time using the ASTRID…
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…
First results of AMBRA: Abundant Seeds and Early Mergers as a Pathway to the First Massive Black Holes
Yihao Zhou, Aklant Kumar Bhowmick, Tiziana Di Matteo +6
AMBRA combines the large cosmological volume and statistical power of ASTRID with the physically motivated gas-based black hole seeding models from BRAHMA. Motivated by JWST's disc…
The Properties of Little Red Dot Galaxies in the ASTRID Simulation
Patrick LaChance, Rupert A. C. Croft, Tiziana Di Matteo +5
We present simulated counterparts of the ``Little Red Dot'' (LRD) galaxies observed with JWST, using the large cosmological hydrodynamic simulation, ASTRID. We create mock observat…
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…
