Formation pathways of the compact stellar systems

J. K. Jang, Sukyoung K. Yi, Soo-Chang Rey +6

The formation pathways of compact stellar systems (CSSs) are still under debate. We utilize the \NH\ simulation to investigate the origins of such objects in the field environment.…

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…

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…

The formation of cores in galaxies across cosmic time -- the existence of cores is not in tension with the LCDM paradigm

R. A. Jackson, S. Kaviraj, S. K. Yi +9

The `core-cusp' problem is considered a key challenge to the LCDM paradigm. Halos in dark matter only simulations exhibit `cuspy' profiles, where density continuously increases tow…

Emergence and cosmic evolution of the Kennicutt-Schmidt relation driven by interstellar turbulence

Katarina Kraljic, Florent Renaud, Yohan Dubois +12

The scaling relations between the gas content and star formation rate of galaxies provide useful insights into processes governing their formation and evolution. We investigate the…

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%…
