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…
ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at
Vandana Ramakrishnan, Ashley Ortiz, Byeongha Moon +52
We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at . These protocluster 'complexes', designated COSMOS-z3.1-A and COS…
Enhancing the Detection Sensitivity of Primordial Parity Violation using Galaxy Spins
Byoungjo Yu, Junsup Shim, Hyunmi Song
It has been recently demonstrated that the signature of primordial parity violation could be imprinted in halo spins, indicating its potential detectability through the late-time g…
The impact of evolving cosmic filaments on mass and spin evolution of dark matter halos
Hannah Jhee, Hyunmi Song, Clotilde Laigle +3
The evolution of galaxies is closely tied to that of their host dark matter halos, which is in turn strongly modulated by the surrounding large-scale environment. Cosmic filaments…
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…
ODIN: Clustering Properties of Ly Blobs at 2.4 and 3.1
Byeongha Moon, Yujin Yang, Eric Gawiser +18
Spatially extended Ly nebulae, known as Ly blobs (LABs), are a rare population at that are thought to trace proto-groups or the progenitors of massive galaxies in t…
