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…

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…

The AGORA High-resolution Galaxy Simulations Comparison Project. XI: Solving the Non-Spherical Morphology and Evolution of Dark Matter Halos with Haskap Pie

Kirk S. S. Barrow, Thinh Huu Nguyen, Santi Roca-FÃ brega +26

We introduce a halo solving and tracking procedure that intrinsically treats dark matter halos as non-spherical objects by leveraging the bound particle searching techniques used i…

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…
