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…
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…
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 inferred component masses in the pair-instability mass gap and exhibits a burst-like morphology with no clearly inspir…
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…
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…
