Primordial Black Holes as Seeds for Extremely Overmassive AGN Observed by JWST
Saiyang Zhang, Boyuan Liu, Volker Bromm +1
The James Webb Space Telescope (JWST) has recently identified Abell 2744-QSO1 as a compact, metal-poor, black hole (BH) dominated galaxy at . This system exhibits an ext…
A Novel Formation Channel for Supermassive Black Hole Binaries in the Early Universe via Primordial Black Holes
Saiyang Zhang, Boyuan Liu, Volker Bromm
We present a novel formation channel for supermassive black hole (SMBH) binaries in the early Universe, driven by primordial black holes (PBHs). Using high-resolution hydrodynamica…
Impact of initial mass function on the chemical evolution of high-redshift galaxies
Boyuan Liu, Michela Mapelli, Volker Bromm +10
Recent observations by the James Webb Space Telescope (JWST) have found evidence for an invariant relation between stellar mass, metallicity, and star formation rate up to $z\sim 8…
A black hole in a near-pristine galaxy 700 million years after the Big Bang
Roberto Maiolino, Hannah Uebler, Francesco D'Eugenio +36
The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpec…
Effects of chemically homogeneous evolution of the first stars on the 21-cm signal and reionization
Boyuan Liu, Daniel Kessler, Thomas Gessey-Jones +6
The first generation of stars, known as Population III (Pop III), played a crucial role in the early Universe through their unique formation environment and metal-free composition.…
How do Massive Primordial Black Holes Impact the Formation of the First Stars and Galaxies?
Saiyang Zhang, Boyuan Liu, Volker Bromm +3
We investigate the impact of massive primordial black holes (PBHs; ) on the star formation and first galaxy assembly process using high-resolution hy…
