Black Hole Occupation Fraction: Dependence on Black Hole Mass Threshold, Environment, Resolution and Redshift
Emanuele Contini, J. K. Jang, Jinsu Rhee +2
We take advantage of the state-of-the-art semi-analytic model \texttt{FEGA25} \citep{contini2025}, run on merger trees extracted from three dark matter-only cosmological simulation…
Introducing NewCluster: the first half of the history of a high-resolution cluster simulation
San Han, Sukyoung K. Yi, Yohan Dubois +8
We introduce NewCluster, a new high-resolution cluster simulation designed to serve as the massive halo counterpart of the modern cosmological galaxy evolution framework. The zoom-…
Roles of Supernova and Active Galactic Nucleus Feedback in Shaping the Baryonic Content in a Wide Range of Dark Matter Halo Masses
Emanuele Contini, Changjo Seo, Jinsu Rhee +2
We build upon FEGA25 (Contini et al 2025), a previously introduced semi-analytic model for galaxy formation and evolution, focusing on its enhanced treatment of supernova and activ…
How Dust Models Shape High-z Galaxy Morphology: Insights from the NewCluster Simulation
Gyeong-Hwan Byun, J. K. Jang, Zachary P. Scofield +10
Dust plays a pivotal role in shaping the observed morphology of galaxies. While traditional cosmological simulations often assume a fixed dust-to-gas (DTG) or dust-to-metal (DTM) m…
Born to be Starless: Revisiting the Missing Satellite Problem
Seyoung Jeon, Sukyoung K. Yi, Emanuele Contini +6
The massive Local Group galaxies both host substantially fewer satellites than the subhalos expected from the cold dark matter paradigm, and the recent investigations have highligh…
A Full AGN Feedback Prescription for Numerical Models: Negative, Positive and Hot Gas-Ejection Modes
Emanuele Contini, Sukyoung K. Yi, Jinsu Rhee +1
We build upon the state-of-the-art semi-analytic model \texttt{FEGA24} (Formation and Evolution of GAlaxies, \citealt{contini2024d}), which integrates the latest prescriptions rele…
