A fast deep-learning approach to probing primordial black hole populations in gravitational wave events
Jun-Qian Jiang, Hai-Long Huang, Jibin He +2
Primordial black holes (PBHs), envisioned as a compelling dark matter candidate and a window onto early-Universe physics, may contribute to some of the gravitational-wave (GW) sign…
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…
Is GW190521 a gravitational wave echo of wormhole remnant from another universe?
Qi Lai, Qing-Yu Lan, Hao-Yang Liu +2
A particularly compelling aspect of the GW190521 event detected by the LIGO--Virgo--KAGRA (LVK) collaboration is that it has an extremely short duration, and lacks a clearly identi…
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…
Sub-Eddington accreting supermassive primordial black holes explain Little Red Dots
Hai-Long Huang, Jun-Qian Jiang, Jibin He +2
The James Webb Space Telescope (JWST) has uncovered an abundant population of compact, extremely red, and X-ray weak objects at , knows as ``Little Red Dots" (LRDs). The…
Supermassive primordial black holes for the GHZ9 and UHZ1 observed by the JWST
Hai-Long Huang, Yu-Tong Wang, Yun-Song Piao
The high redshift () galaxies GHZ9 and UHZ1 observed by the James Webb Space Telescope (JWST) are very massive and have exceptionally high black hole-to-star mass ratios with…
