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-…

Rapid emergence of overmassive black holes in the early Universe

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…

Statistical Properties of Cold Streams In Massive Star-Forming Halos in TNG50

Isabel Medlock, Daisuke Nagai, Nir Mandelker +4

Cold, dense streams of gas are predicted to penetrate deeply into massive halos (> 10^12 Msun) at cosmic noon (z=4-2), fueling galaxies to sustain high star formation rates. We inv…

Constraints on the early growth of massive black holes from PTA and JWST with L-GalaxiesBH

Silvia Bonoli, David Izquierdo-Villalba, Daniele Spinoso +4

Recent Pulsar Timing Arrays (PTAs) results provided strong evidence for a stochastic gravitational wave background (sGWB), consistent with a population of merging massive black hol…

NOEMA: A first kpc resolution study of a main sequence barred galaxy channeling gas into a growing bulge

Stavros Pastras, Reinhard Genzel, Linda J. Tacconi +32

We present a very deep CO(3-2) observation of a massive, gas-rich, main sequence, barred spiral galaxy at . Our data were taken with the IRAM-NOEMA interferometer for…
