  • New Horizon: On the Origin of the Stellar Disk and Spheroid of Field Galaxies at z = 0.7 
    Park, Min-Jung; Yi, Sukyoung K; Dubois, Yohan; Pichon, Christophe; Kimm, Taysun; Devriendt, Julien; Choi, Hoseung; Volonteri, Marta; Kaviraj, Sugata; Peirani, Sebastien (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The origin of the disk and spheroid of galaxies has been a key open question in understanding their morphology. Using the high-resolution cosmological simulation New Horizon, we explore kinematically decomposed disk and ...
  • Star–Gas Misalignment in Galaxies. I. The Properties of Galaxies from the Horizon-AGN Simulation and Comparisons to SAMI 
    Khim, Donghyeon J.; Yi, Sukyoung K; Dubois, Yohan; Bryant, Julia J.; Pichon, Christophe; Croom, Scott M.; Bland-Hawthorn, Joss; Brough, Sarah; Choi, Hoseung; Devriendt, Julien; Groves, Brent; Owers, Matt S.; Richards, Samuel N.; van de Sande, Jesse; Sweet, Sarah M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Recent integral field spectroscopy observations have found that about 11% of galaxies show star–gas misalignment. The misalignment possibly results from external effects such as gas accretion, interaction with other objects, ...
