Star-Gas Misalignment in Galaxies: II. Origins Found from the Horizon-AGN Simulation
Donghyeon J. Khim, Sukyoung K. Yi, Christophe Pichon +5
There have been many studies aiming to reveal the origins of the star-gas misalignment found in galaxies, but there still is a lack of understanding of the contribution from each f…
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…
Exploring the origin of thick disks using the NewHorizon and Galactica simulations
Minjung J. Park, Sukyoung K. Yi, Sebastien Peirani +8
Ever since a thick disk was proposed to explain the vertical distribution of the Milky Way disk stars, its origin has been a recurrent question. We aim to answer this question by i…
Introducing the NewHorizon simulation: Galaxy properties with resolved internal dynamics across cosmic time
Yohan Dubois, Ricarda Beckmann, Frédéric Bournaud +13
Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics. However, us…
The role of mergers and interactions in driving the evolution of dwarf galaxies over cosmic time
G. Martin, R. A. Jackson, S. Kaviraj +9
Dwarf galaxies (M*<10^9 Msun) are key drivers of mass assembly in high mass galaxies, but relatively little is understood about the assembly of dwarf galaxies themselves. Using the…
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…
