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…
Small-scale Lyman alpha forest cosmology with PRIYA: Constraints from XQ100 and KODIAQ-SQUAD one-dimensional flux power spectra
Ming-Feng Ho, Mahdi Qezlou, Simeon Bird +4
We present a new cosmological analysis of the small-scale Lyman alpha forest 1D flux power spectrum (P1D) using high-resolution quasar spectra from XQ100 and KODIAQ-SQUAD, interpre…
Design and optimization of neural networks for multifidelity cosmological emulation
Yanhui Yang, Simeon Bird, Ming-Feng Ho +1
Accurate and efficient simulation-based emulators are essential for interpreting cosmological survey data down to nonlinear scales. Multifidelity emulation techniques reduce simula…
Ten-dimensional neural network emulator for the nonlinear matter power spectrum
Yanhui Yang, Simeon Bird, Ming-Feng Ho +1
We present GokuNEmu, a ten-dimensional neural network emulator for the nonlinear matter power spectrum, designed to support next-generation cosmological analyses. Built on the Goku…
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…
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…
