A Universal Relation Between Primordial Density-Potential Cross-correlation Coefficient and Spin Factor Distribution
Jun-Sung Moon, Jounghun Lee, Juhan Kim
The authors derive an analytic expression that relates the mean and variance of the primordial spin factor of dark matter halos to the initial density‑potential cross‑correlation c…
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…
cuRAMSES: Scalable AMR Optimizations for Large-Scale Cosmological Simulations
Juhan Kim
We present cuRAMSES, a suite of advanced domain decomposition strategies and algorithmic optimizations for the ramses adaptive mesh refinement (AMR) code, designed to overcome the…
ODIN: Rest-frame Optical Morphologies and Star Formation Activity of Lyα Emitters at z=2.4, 3.1, and 4.5
Sang Hyeok Im, Ho Seong Hwang, Jeong Hwan Lee +19
We analyze the rest-frame optical (~8000 Å) morphologies and star formation activity of Lyα emitters (LAEs) at redshifts , , and , identified in the ODIN survey. To…
The Critical Mass in Galaxy Evolution
Preetish K. Mishra, Changbom Park, Jaehyun Lee +4
We investigate the physical origin of critical mass, a threshold where many galaxy properties and scaling relations undergo fundamental transitions, using the Horizon Run 5 simulat…
Closing the Observational Gap in Cosmic Dynamics: AI-Enabled Reconstruction of the Universe's Vorticity and Rotational Flow Morphology
Ziyong Wu, Xu Xiao, Fuyu Dong +7
The cosmic vorticity field, an essential tracer of nonlinear structure formation, has remained observationally inaccessible because transverse galaxy motions are difficult to measu…
