Invariant manifolds in barred galaxy simulations. I. Material density waves
Toni Soler-Terricabras, Mercè Romero-Gómez, Santi Roca-Fà brega
We investigate the dynamical origin and kinematic signatures of spiral structure in an N-body simulation of an isolated barred galaxy, assessing whether invariant manifold theory p…
The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier
Hyeonyong Kim, Ji-hoon Kim, Minyong Jung +22
Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at…
Survival or Destruction: Effects of Spheroidal Satellite Collisions on Bars in Milky Way-Like Galaxies
Yufan Zhou, Zhiyuan Li, Ãscar Jiménez-Arranz +1
Although stellar bars are prevalent in local galaxies, unbarred galaxies constitute a significant fraction, particularly at high redshifts. While some galaxies are unbarred by natu…
VINTERGATAN-GM: long-lived satellite planes induced by a massive GSE-like merger
R. RodrÃguez-Cardoso, S. Roca-FÃ brega, Oscar Agertz +7
Satellite galaxies in the Local Group tend to be distributed in thin, planar configurations, with many sharing coherent orbital motion. Galaxy formation simulations in CDM have…
Tidally-induced radial migration waves in LMC-like galaxies
Dylan Hebrail, Ãscar Jiménez-Arranz, Santi Roca-Fà brega
Stellar radial migration has predominantly been examined in isolated disc galaxies where non-axisymmetric structures drive the process. By contrast, while tidal interactions are kn…
The AGORA High-resolution Galaxy Simulations Comparison Project. VIII: Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at
Minyong Jung, Ji-hoon Kim, Thinh H. Nguyen +24
We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 , using eight state-of-the-art…
