Kinematic scaling of thin and thick discs from SAMI to NewHorizon

Sree Oh, J. K. Jang, Giulia Santucci +8

We revisit the relation between disc stellar mass and disc velocity dispersion (M_*-σ_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SA…

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…

On the Origin of Intracluster Light based on the High-resolution Simulation, NewCluster

Seyoung Jeon, Emanuele Contini, San Han +11

Intracluster light (ICL) is a key component of galaxy clusters, with the potential to trace their dynamical assembly histories and the underlying dark matter distribution. Despite…

On the Origin of Gas-stripping of Galaxies in Group Environments

Jinsu Rhee, Christophe Pichon, Yohan Dubois +12

We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…

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-…

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…
