Galaxies in the first two billion years: Earlier formation and quenching with surface-density modulated star formation and feedback
Akash Vani, Mohammadreza Ayromlou, Guinevere Kauffmann +1
JWST has revealed massive, UV-bright, compact, and in some cases quenched galaxies in the first two billion years of cosmic history, challenging current galaxy formation models. We…
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-…
Overmassive black holes and little red dots naturally form in simulations
Sunmyon Chon, Shingo Hirano, Tomoaki Ishiyama +2
The origin of supermassive black holes (SMBHs) remains a long-standing problem in astrophysics. Recent JWST observations reveal an unexpectedly abundant population of overmassive b…
