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…
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…
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-…
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 Star Formation Quenching of Galaxies in Group Environments using the NewHorizon simulation
Jinsu Rhee, Sukyoung K. Yi, Jongwan Ko +8
We study star formation (SF) quenching of satellite galaxies with within two low-mass groups ( and ) using t…
Feeding Hidden Monsters: a Super-Eddington accreting Black Hole ~1.5 Gyr after the Big Bang
Hyewon Suh, Julia Scharwächter, Emanuele Paolo Farina +13
Recent James Webb Space Telescope (JWST) observations have revealed a surprisingly abundant population of faint, dusty active galactic nuclei (AGNs) at z~4-7. Together with the pre…
Diffuse Light in Milky-Way like Haloes
E. Contini, S. Han, S. Jeon +2
We investigate the diffuse light (DL) content of dark matter haloes in the mass range , a range that includes also the dark matter halo of the Milky-W…
Galaxies with grains: unraveling dust evolution and extinction curves with hydrodynamical simulations
Yohan Dubois, Francisco Rodríguez Montero, Corentin Guerra +6
We introduce a model for dust evolution in the RAMSES code for simulations of galaxies with a resolved multiphase interstellar medium. Dust is modelled as a fluid transported with…
Cosmic evolution of black hole-spin and galaxy orientations: clues from the NewHorizon and Galactica simulations
Sebastien Peirani, Yasushi Suto, Ricarda S. Beckmann +10
(Reduced) Using the recent cosmological high-resolution zoom-in simulations, NewHorizon and Galactica, in which the evolution of black hole spin is followed on the fly, we have tra…
The Connection between the Intracluster Light and its Host Halo: Formation Time and Contribution from Different Channels
Emanuele Contini, Jinsu Rhee, San Han +2
We extend the analysis presented in \cite{contini2023a} to higher redshifts, up to , by focusing on the relation between the intracluster light (ICL) fraction and the halo mas…
The Intracluster Light and its Link with the Dynamical State of the Host Group/Cluster: the Role of the Halo Concentration
E. Contini, S. Jeon, J. Rhee +2
We investigate on the role of the halo concentration in the formation of the intra-cluster light (ICL) in galaxy groups and clusters, as predicted by a state-of-art semi-analytic m…
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…
On the Significance of the Thick Disks of Disk Galaxies
Sukyoung K. Yi, J. K. Jang, Julien Devriendt +8
Thick disks are a prevalent feature observed in numerous disk galaxies including our own Milky Way. Their significance has been reported to vary widely, ranging from a few to 100%…
Star formation history and transition epoch of cluster galaxies based on the Horizon-AGN simulation
Seyoung Jeon, Sukyoung Yi, Yohan Dubois +7
Cluster galaxies exhibit substantially lower star formation rates than field galaxies today, but it is conceivable that clusters were sites of more active star formation in the ear…
YZiCS: On the Mass Segregation of Galaxies in Clusters
Seonwoo Kim, Emanuele Contini, Hoseung Choi +5
Mass segregation, a tendency of more massive galaxies being distributed closer to the cluster center, is naturally expected from dynamical friction, but its presence is still contr…
YZiCS: Unveiling Quenching History of Cluster Galaxies Using Phase-space Analysis
Jinsu Rhee, Rory Smith, Hoseung Choi +4
We used the time since infall (TSI) of galaxies, obtained from the Yonsei Zoom-in Cluster Simulation, and the star formation rate (SFR) from the Sloan Digital Sky Survey (SDSS) Dat…
YZiCS: Preprocessing of dark halos in the hydrodynamic zoom-in simulation of clusters
San Han, Rory Smith, Hoseung Choi +4
To understand the galaxy population in clusters today, we should also consider the impact of previous environments prior to cluster infall, namely preprocessing. We use YZiCS, a hy…
