Constraining supermassive primordial black hole clustering with the angular auto-correlation of quasars
Zhan-He Wang, Hai-Long Huang, Yun-Song Piao
High-redshift quasars provide a direct probe of the origin and environment of the earliest supermassive black holes. We use their angular auto-correlation function at t…
Testing the wormhole echo hypothesis for GW231123
Qi Lai, Qing-Yu Lan, Zhan-He Wang +1
The short-duration gravitational-wave (GW) event GW231123 has component masses inferred to lie in the pair-instability mass gap and exhibits a burst-like morphology without a clear…
DeepInflation: an AI agent for research and model discovery of inflation
Ze-Yu Peng, Hao-Shi Yuan, Qi Lai +4
We present DeepInflation, an AI agent designed for research and model discovery in inflationary cosmology. Built upon a multi-agent architecture, DeepInflation integrates Large Lan…
Gravitomagnetic-Hydrodynamics and Turbulence in Early Universe
Jiaxiang Liang, Peng Xu, Minghui Du +4
The nonlinear coupling between spacetime geometry and matter in the early Universe remains a frontier in theoretical cosmology. By introducing a novel gravitomagnetic-hydrodynamic…
News-Aware Direct Reinforcement Trading for Financial Markets
Qing-Yu Lan, Zhan-He Wang, Jun-Qian Jiang +2
The financial market is known to be highly sensitive to news. Therefore, effectively incorporating news data into quantitative trading remains an important challenge. Existing appr…
Search for primordial black holes from gravitational wave populations using deep learning
Hai-Long Huang, Zhan-He Wang, Qing-Yu Lan +5
Gravitational waves (GWs) signals detected by the LIGO/Virgo/KAGRA collaboration might be sourced (partly) by the merges of primordial black holes (PBHs). The conventional hierarch…
Broad primordial power spectrum and -distortion constraints on primordial black holes
Zhan-He Wang, Hai-Long Huang, Yun-Song Piao
Supermassive black holes (SMBHs) might originate from supermassive primordial black holes (PBHs). However, the hypothesis that these PBHs formed through the enhancement of the prim…
