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…

Cluster vs Field: Clear Evidence for a Morphology-Density Relation in All Environments at

Westley Brown, Adam Muzzin, Jasleen Matharu +6

We explore the relationship between galaxy structure, stellar mass, and local galaxy density in three SpARCS clusters at and compare with field galaxies from the 3D-HST…

Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts

Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54

The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…

Distinct origins of environmentally quenched galaxies in the core and outer virialised regions of massive clusters at

Guillaume Hewitt, Florian Sarron, Michael L. Balogh +15

High-redshift () galaxy clusters are the domain where environmental quenching mechanisms are expected to emerge as important factors in the evolution of the quiescent galax…

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…

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…
