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…

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…

On the Origin of the Variety of Velocity Dispersion Profiles of Galaxies

San Han, Sukyoung K. Yi, Sree Oh +8

Observed and simulated galaxies exhibit a significant variation in their velocity dispersion profiles. We examine the inner and outer slopes of stellar velocity dispersion profiles…
