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…
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…
Large-scale surveys of the quasar proximity effect
Rupert A. C. Croft, Patrick Shaw, Ann-Marsha Alexis +6
The UV radiation from high redshift quasars causes a local deficit in the neutral hydrogen absorption (Lyman-alpha forest) in their spectra, known as the proximity effect. Measurem…
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…
