Constructing a Mock Galaxy Catalog for the All-sky SPECtroscopic Survey of Nearby Galaxies (A-SPEC) Using the Machine-assisted Semi-Simulation Model
Dongkok Kim, Yongseok Jo, Ho Seong Hwang +26
We present a methodology for constructing a mock galaxy catalog for the All-sky SPECtroscopic survey of nearby galaxies (A-SPEC) using the Machine-assisted Semi-Simulation Model. T…
Learning the Universe with the 2nd Generation of CAMELS: Varying 35 parameters of the IllustrisTNG model in (50Mpc/h)^3 boxes
Shy Genel, Yongseok Jo, Boon Kiat Oh +10
We present a new set of 1,192 cosmological simulations as part of the CAMELS project, in which a space of 35 cosmological, astrophysical, and numerical parameters is explored aroun…
From Dense Gas Clouds to Supermassive Black Hole Seeds: Hybrid Hydro/Direct -body Simulations of Runaway Collision-driven Intermediate-mass Black Hole Formation
Eunwoo Chung, Yongseok Jo, Ji-hoon Kim +2
A population of dense stellar systems at high redshift has recently been uncovered by the JWST. To investigate the formation of supermassive black hole (SMBH) seeds in these dense…
Evolution of Nuclear Star Cluster in Dwarf Galaxy through Mergers and In-Situ Star Formation
Yongseok Jo, Minyong Jung, Greg L. Bryan +3
Nuclear Star Clusters (NSCs) are dense stellar systems located at the centers of galaxies. Employing Enzo-Abyss, which integrates hydrodynamics with a direct N-body solver, we intr…
Towards Robustness Across Cosmological Simulation Models TNG, SIMBA, ASTRID, and EAGLE
Yongseok Jo, Shy Genel, Anirvan Sengupta +3
The rapid advancement of large-scale cosmological simulations has opened new avenues for cosmological and astrophysical research. However, the increasing diversity among cosmologic…
On the Significance of Covariance for Constraining Theoretical Models From Galaxy Observables
Yongseok Jo, Shy Genel, Joel Leja +1
In this study, we investigate the impact of covariance within uncertainties on the inference of cosmological and astrophysical parameters, specifically focusing on galaxy stellar m…
