In-situ vs. ex-situ drivers of galaxy quenching: ubiquity of main sequence and critical black hole mass from the FLAMINGO simulation

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Seunghwan Lim, Sandro Tacchella, Roberto Maiolino, Joop Schaye, Matthieu Schaller | Summary: Exploiting a large sample of 5.3 million galaxies with $M_ast,{=},10^{10-11},{rm M}_odot$ from the highest-resolution FLAMINGO simulation, we carry out a statistical analysis of quiescent and star-forming galaxies to explore quenching mechanisms. From redshift $z,{simeq},7$ to […]

Effects of chemically homogeneous evolution of the first stars on the 21-cm signal and reionization

Kavli Affiliate: George Efstathiou | First 5 Authors: Boyuan Liu, Daniel Kessler, Thomas Gessey-Jones, Jiten Dhandha, Anastasia Fialkov | Summary: The first generation of stars, known as Population III (Pop III), played a crucial role in the early Universe through their unique formation environment and metal-free composition. These stars can undergo chemically homogeneous evolution (CHE) […]

The dawn of disks: unveiling the turbulent ionised gas kinematics of the galaxy population at $zsim4-6$ with JWST/NIRCam grism spectroscopy

Kavli Affiliate: Roberto Maiolino | First 5 Authors: A. Lola Danhaive, Sandro Tacchella, Hannah Übler, Anna de Graaff, Eiichi Egami | Summary: Recent studies of gas kinematics at high redshift have reported disky systems which appear to challenge models of galaxy formation, but it is unclear whether they are representative of the underlying galaxy population.
