The lifetimes and properties of Little Red Dots in the AMBRA simulation
Patrick LaChance, Yihao Zhou, Aklant Kumar Bhowmick +6
We identify and analyze the little red dots (LRDs) in the AMBRA cosmological hydrodynamic simulation, by producing mock observations of the galaxies and active galactic nuclei (AGN…
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…
Matter Clustering in Astrid: Reduced Baryonic Suppression from Realistic Black Hole Dynamics
Yanhui Yang, Simeon Bird, Yihao Zhou +4
Baryonic feedback from active galactic nuclei (AGN) is often invoked as a major source of suppression in the matter power spectrum, with implications for precision cosmology and th…
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…
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…
From ASTRID to BRAHMA -- The role of overmassive black holes in little red dots in cosmological simulations
Patrick LaChance, Aklant Kumar Bhowmick, Rupert A. C. Croft +8
We leverage the overmassive black holes () present in a realization of the BRAHMA cosmological hydrodynamic simulation suite to investigate their ro…
The ASTRID Simulation at z=0: From Massive Black Holes to Large-scale Structure
Yihao Zhou, Tiziana Di Matteo, Simeon Bird +7
We present the results for the cosmological simulation ASTRID. Hosting 0.33 trillion particles in a box of per side, ASTRID is one o…
Gravitational Waves from Massive Black Hole Mergers in ASTRID: Predictions for LISA
Bonny Y. Wang, Yihao Zhou, William Chen +5
We use the ASTRID cosmological simulation to forecast massive black hole (MBH) mergers detectable by Laser Interferometer Space Antenna (LISA) down to . ASTRID directly models…
The Gravitational Wave Background from Massive Black Holes in the ASTRID Simulation
Nianyi Chen, Tiziana Di Matteo, Yihao Zhou +6
Recent pulsar timing array (PTA) observations have detected nanohertz gravitational waves, likely originating from massive black hole binaries (MBHBs). The detected amplitude is un…
Central Cluster Galaxies: A Hotspot for Detectable Gravitational Waves from Black Hole Mergers
Yihao Zhou, Tiziana Di Matteo, Nianyi Chen +6
After Pulsar Timing Arrays (PTAs) have announced the evidence for a low-frequency gravitational wave background (GWB), the continuous waves (CWs) are the next anticipated gravitati…
MAGICS II. Seed black holes stripped of their surrounding stars do not sink
