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…
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…
Cyclic Zoom: Multiscale GRMHD Modeling of Black Hole Accretion and Feedback
Minghao Guo, James M. Stone, Eliot Quataert +1
We present a ``cyclic zoom'' method to capture the dynamics of accretion flows onto black holes across a vast range of spatial and temporal scales in general relativistic magnetohy…
Pearls on a string: Dark and bright galaxies on a strikingly straight and narrow filament
Maryam Arabsalmani, Sambit Roychowdhury, Benjamin Schneider +11
We identify a chain of galaxies along an almost straight line in the nearby Universe with a projected length of ~5 Mpc. The galaxies are distributed within projected distances of o…
Probing galaxy evolution from to through galaxy scaling relations in three L-Galaxies flavours
Akash Vani, Mohammadreza Ayromlou, Guinevere Kauffmann +1
We present a comprehensive examination of the three latest versions of the L-Galaxies semi-analytic galaxy formation model, focusing on the evolution of galaxy properties across a…
