Ongoing Morphological Transformation from Elliptical to Spiral Galaxies Induced by Gas Accretion from Neighboring Galaxies
Gene Yun, Sang Hyeok Im, Ho Seong Hwang +2
We present results from spectroscopic observations of three interacting galaxy systems, each associated with a primary galaxy - VCC 1748, SDSS J1106, and 2MASX J0834 - which have b…

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 the…
ODIN: Using multiplicity of Lyman-Alpha Emitters to assess star formation activity in dark matter halos
M. Candela Cerdosino, Nelson Padilla, Ana Laura O'Mill +16
We investigate if systems of multiple Lyman-alpha emitters (LAEs) can serve as a proxy for dark matter halo mass, assess how their radiative properties relate to the underlying hal…
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…
A Redshift Survey of the Coma Cluster (A1656): Understanding the Nature of Subhalos in the Weak-lensing Map
Wooseok Kang, Ho Seong Hwang, Nobuhiro Okabe +1
We study the physical properties of weak-lensing subhalos in the Coma cluster of galaxies using data from galaxy redshift surveys. The data include 12989 galaxies with measured spe…
ODIN: Clustering Analysis of 14,000 Lyα Emitting Galaxies at z=2.4, 3.1, and 4.5
Danisbel Herrera, Eric Gawiser, Barbara Benda +15
Lyman Alpha Emitters (LAEs) are star-forming galaxies that efficiently probe the spatial distribution of galaxies in the high redshift universe. The spatial clustering of LAEs refl…
The Role of Large-Scale Environment in Shaping the Stellar Mass-Gas Metallicity Relation Across Time
Aaron R. Rowntree, Fiorenzo Vincenzo, Ankit Singh +8
We study the stellar mass-gas metallicity relation (MZR) which shows a significant scatter for a fixed stellar mass. By defining global environments, nodes, filaments, and voids wi…
ODIN: Star Formation Histories Reveal Formative Starbursts Experienced by Lyman Alpha Emitting Galaxies at Cosmic Noon
Nicole M. Firestone, Eric Gawiser, Kartheik G. Iyer +27
In this work, we test the frequent assumption that Lyman Alpha Emitting galaxies (LAEs) are experiencing their first major burst of star formation at the time of observation. To th…
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…
