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…
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.…
The Emerging Black Hole Mass Function in the High-Redshift Universe
Junehyoung Jeon, Boyuan Liu, Anthony J. Taylor +5
Observations with the James Webb Space Telescope (JWST) have identified an abundant population of supermassive black holes (SMBHs) already in place during the first few hundred mil…
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…
Primordial black holes as dark matter candidates: Multi-frequency constraints from cosmic radiation backgrounds
C. Casanueva-Villarreal, N. Padilla, P. B. Tissera +2
Aims. This study investigates the role of primordial black holes (PBHs) in shaping cosmic radiation backgrounds--the cosmic X-ray background (CXB), the Lyman-Werner background (LWB…
Magnetic fields limit the mass of Population III stars even before the onset of protostellar radiation feedback
Piyush Sharda, Shyam H. Menon, Roman Gerasimov +5
The masses of Population III stars are largely unconstrained since no simulations exist that take all relevant primordial star formation physics into account. We perform the first…
