Emergence of the Galaxy Morphology-Star Formation Activity-Clustercentric Radius Relations in Galaxy Clusters
Sungwook E. Hong, Changbom Park, Preetish K. Mishra +7
We investigate when and how the relations of galaxy morphology and star forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy cluste…
Quenching of Galaxies at Cosmic Noon: Understanding the Effect of Environment
Akriti Singh, Lucia Guaita, Pascale Hibon +16
The aim of this study is to identify quiescent galaxies in the 2-deg COSMOS field at and analyze their environment. Using data from the ODIN survey and COSMOS2020…
Tracing the Formation History of Intrahalo Light with Horizon Run 5
Hyungjin Joo, M. James Jee, Juhan Kim +8
We investigate the formation history of intrahalo light (IHL) using the high-resolution (~1 kpc), large-scale (~Gpc) cosmological hydrodynamical simulation, Horizon Run 5 (HR5). IH…
ODIN: Strong Clustering of Protoclusters at Cosmic Noon
Vandana Ramakrishnan, Kyoung-Soo Lee, Nicole Firestone +15
The One-hundred-deg DECam Imaging in Narrowbands (ODIN) survey is carrying out a systematic search for protoclusters during Cosmic Noon, using Ly-emitting galaxies (LAEs) as…
Topological approach to void finding applied to the SDSS galaxy map
Manu Aggarwal, Motonari Tonegawa, Stephen Appleby +2
The structure of the low redshift Universe is dominated by a multi-scale void distribution delineated by filaments and walls of galaxies. The characteristics of voids; such as morp…
Testing Lyman Alpha Emitters and Lyman-Break Galaxies as Tracers of Large-Scale Structures at High Redshifts
Sang Hyeok Im, Ho Seong Hwang, Jaehong Park +21
We test whether Lyman alpha emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamica…
ODIN: Identifying Protoclusters and Cosmic Filaments Traced by Ly-emitting Galaxies
Vandana Ramakrishnan, Kyoung-Soo Lee, Maria Celeste Artale +22
To understand the formation and evolution of massive cosmic structures, studying them at high redshift, in the epoch when they formed the majority of their mass is essential. The O…
A Deep Redshift Survey of the Perseus Cluster: Spatial Distribution and Kinematics of Galaxies
Wooseok Kang, Ho Seong Hwang, Hyunmi Song +3
We study the global kinematics of the Perseus galaxy cluster (Abell 426) at redshift z = 0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation…
