Probing the influence of the protocluster environment on galaxy morphology at z = 2.23
Emmet Golden-Marx, Zheng Cai, Dongdong Shi +7
As galaxies evolve in dense cluster and protocluster environments, they interact and quench their star formation, which gradually transforms the galaxy population from star-forming…
The HST-Hyperion Survey: Environmental Imprints on the Stellar-Mass Function at z~2.5
Derek Sikorski, Ben Forrest, Brian C. Lemaux +19
Not all galaxies at Cosmic Noon evolve in the same way. It remains unclear how the local environment -- especially the extreme overdensities of protoclusters -- affects stellar mas…
A 13-Billion-Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to with JWST and Archival Surveys
Zihao Li, Zheng Cai, Xin Wang +25
The galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and high-redshift universe, as they trace the baryon cycle an…
Gas properties as a function of environment in the proto-supercluster Hyperion at z ~ 2.45
G. Gururajan, O. Cucciati, B. C. Lemaux +26
The cosmic star-formation rate density, molecular gas density and the AGN activity of the Universe peak at z~ 2-3, showing the Universe is most active at this epoch. The nature of…
Quantifying the Impact of Incompleteness on Identifying and Interpreting Galaxy Protocluster Populations with the TNG-Cluster Simulation
Devontae C. Baxter, Alison L. Coil, Ethan O. Nadler +7
We use the TNG-Cluster simulation to investigate how stellar mass and star formation rate (SFR) incompleteness affect the identification of density peaks within galaxy protocluster…
HST Grism Observations of a z~1.8 Cluster Candidate from the Clusters Occupied by Bent Radio AGN (COBRA) Survey
Courtney B. Watson, Elizabeth L. Blanton, Emmet Golden-Marx +4
We present new Hubble Space Telescope/Wide Field Camera 3 G141 grism observations for COBRA1411+3415, originally identified as a high-redshift cluster candidate in the Clusters Occ…
The HST-Hyperion Survey: Grism Observations of a Proto-Supercluster
Ben Forrest, Lu Shen, Brian C. Lemaux +19
We present first results and catalogs from the HST-Hyperion survey. This survey has collected 50 orbits of WFC3/F160W imaging and WFC3/G141 grism spectroscopy in the most overdense…
The HST-Hyperion Survey: Companion Fraction and Overdensity in a z ~ 2.5 Proto-supercluster
F. Giddings, B. C. Lemaux, B. Forrest +22
We present a study of the galaxy merger and interaction activity within the Hyperion Proto-supercluster at z~2.5 in an effort to assess the occurrence of galaxy mergers and interac…
Discovering Large-Scale Structure at in the C3VO Survey
Denise Hung, Brian C. Lemaux, Olga Cucciati +23
The Charting Cluster Construction with VUDS and ORELSE (C3VO) survey is an ongoing imaging and spectroscopic campaign aiming to map out the growth of structure up to and w…
Enhanced AGN Activity in Overdense Galactic Environments at
Ekta A. Shah, Brian C. Lemaux, Benjamin Forrest +17
We conduct a study on the relationship between galaxy environments and their active galactic nuclei (AGN) activity at high redshifts (). Specifically, we study the AGN f…
Environmental Effects on the Stellar Mass Function in a z~3.3 Overdensity of Galaxies in the COSMOS Field
Ben Forrest, Brian C. Lemaux, Ekta A. Shah +17
We present an analysis of the number density of galaxies as a function of stellar mass (i.e., the stellar mass function, SMF) in the COSMOS field at z~3.3, making a comparison betw…
Searching for [CII] Emission from the First Sample of OI Absorption-Associated Galaxies with ALMA
Yunjing Wu, Zheng Cai, Jianan Li +13
We report the first statistical analyses of [CII] and dust continuum observations in six strong OI absorber fields at the end of the reionization epoch obtained by the Atacama Larg…
The High-Redshift Clusters Occupied by Bent Radio AGN (COBRA) Survey: Investigating the Role of Environment on Bent Radio AGNs using LOFAR
Emmet Golden-Marx, Emily Moravec, Lu Shen +10
Bent radio AGN morphology depends on the density of the surrounding gas. However, bent sources are found inside and outside clusters, raising the question of how environment impact…
Inspiraling streams of enriched gas observed around a massive galaxy 11 billion years ago
Shiwu Zhang, Zheng Cai, Dandan Xu +19
Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas-the reaccretion of gas that was previously eject…
VLA resolves unexpected radio structures in the Perseus cluster of galaxies
Marie-Lou Gendron-Marsolais, Charles L. H. Hull, Rick Perley +10
We present new deep, high-resolution, 1.5 GHz observations of the prototypical nearby Perseus galaxy cluster from the Karl G. Jansky Very Large Array. We isolate for the first time…
The High-Redshift Clusters Occupied by Bent Radio AGN (COBRA) Survey: Radio Source Properties
Emmet Golden-Marx, Elizabeth Blanton, Rachel-Paterno-Mahler +8
The shape of bent, double-lobed radio sources requires a dense gaseous medium. Bent sources can therefore be used to identify galaxy clusters and characterize their evolutionary hi…
Extended radio AGN at z ~ 1 in the ORELSE survey: The confining effect of dense environments
Lu Shen, Guilin Liu, Mengfei Zhang +16
Recent hydrodynamic simulations and observations of radio jets have shown that the surrounding environment has a large effect on their resulting morphology. To investigate this we…
