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…
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…
Influence of supermassive primordial black holes on ultraviolet luminosity of high-redshift galaxies
Yi-Yang Li, Hai-Long Huang, Yun-Song Piao
Recently James Webb Space Telescope (JWST) have observed an excess of luminous galaxies at high redshifts (). In this work, we investigate whether supermassive primor…
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…
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…
