Formation of Heavy Seed Black Holes and Little Red Dots-like Compact Clusters in Metal-enriched Star-forming Regions
Sunmyon Chon, Shingo Hirano, Ke-Jung Chen +1
The origin of supermassive black holes (SMBHs) in the early Universe remains uncertain. While the classical direct-collapse scenario requires pristine gas exposed to intense Lyman-…
Supernova feedback in porous photoionized Giant Molecular Clouds
Cheryl S. C. Lau, Ian A. Bonnell, Yueh-Ning Lee +1
We present a new suite of numerical simulations of Type II supernovae (SNe) detonating in Giant Molecular Clouds with a variety of density structures shaped by photoionization feed…
Clumpy Structures within the Turbulent Primordial Cloud
Ching-Yao Tang, Ke-Jung Chen
The primordial clouds in the mini-halos hatch the first generation stars of the universe, which play a crucial role in cosmic evolution. In this paper, we investigate how the turbu…
How Population III Supernovae Determined the Properties of the First Galaxies
Ke-Jung Chen, Ching-Yao Tang, Daniel J. Whalen +4
Massive Pop III stars can die as energetic supernovae that enrich the early universe with metals and determine the properties of the first galaxies. With masses of about Msu…
Rapid Growth of Galactic Supermassive Black Holes through Accreting Giant Molecular Clouds during Major Mergers of their Host Galaxies
Chi-Hong Lin, Ke-Jung Chen, Chorng-Yuan Hwang
Understanding the formation of the supermassive black holes (SMBHs) present in the centers of galaxies is a crucial topic in modern astrophysics. Observations have detected the SMB…
Magnetic Fields in Primordial Galaxies
Huai-Hsuan Chiu, Ke-Jung Chen
Magnetic fields play a vital role in numerous astrophysical processes such as star formation and the interstellar medium. In particular, their role in the formation and evolution o…
How the Population III Initial Mass Function Governs the Properties of the First Galaxies
Li-Hsin Chen, Ke-Jung Chen, Sung-han Tsai +1
The properties of Population III (Pop III) stars impact many aspects of primeval structure formation such as the onset of cosmological reionization and early chemical enrichment. H…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
How the First Stars Regulated Star Formation. II. Enrichment by Nearby Supernovae
Ke-Jung Chen, Daniel J. Whalen, Katharina M. J. Wollenberg +2
Metals from Population III (Pop III) supernovae led to the formation of less massive Pop II stars in the early universe, altering the course of evolution of primeval galaxies and c…
Cosmological Impact of Population III Binaries
Ke-Jung Chen, Volker Bromm, Alexander Heger +2
We present the results of the stellar feedback from Pop III binaries by employing improved, more realistic Pop III evolutionary stellar models. To facilitate a meaningful compariso…
