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…
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…
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…
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…
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…
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…
