The Brightest UV-selected Galaxies in Protoclusters at z ∼ 4: Ancestors of Brightest Cluster Galaxies? [PDF]

, 2019
We present the results of a survey of the brightest UV-selected galaxies in protoclusters. These proto-brightest cluster galaxy (proto-BCG) candidates are drawn from 179 overdense regions of g-dropout galaxies at z ∼ 4 from the Hyper Suprime-Cam Subaru ...

LATIS: A Sample of IGM-selected Protoclusters and Protogroups at z ∼ 2.5

The Astrophysical Journal
The Ly α Tomography IMACS Survey (LATIS) has produced large 3D maps of the intergalactic medium (IGM), providing a new window on the cosmic web at z ∼ 2.5.

A Massive Protocluster Anchored by a Luminous Quasar at z = 6.63

The Astrophysical Journal Letters
Protoclusters, the progenitors of galaxy clusters, trace large scale structures in the early Universe and are important to our understanding of structure formation and galaxy evolution. To date, only a handful of protoclusters have been identified in the

Protocluster survey/characterization with NGRST

, 2021
Protoclusters are interesting laboratories of galaxy evolution. To study their typical properties, first of all, deep and wide surveys are required since their surface density is quite small (a few in deg^2). Based on the deep and wide survey in optical by Hyper Suprime-Cam Subaru Strategic Program, the largest (N=179 in 121 deg^2) and uniform catalog ...

High-Redshift Protoclusters Traced by Submillimeter Galaxies [PDF]

, 2017
Radio galaxies have been used quite successfully as protocluster tracers. However, because they are only visible for a short period in the evolution of a massive galaxy, a significant fraction of forming clusters remains unexplored.

Quantifying the Impact of Incompleteness on Identifying and Interpreting Galaxy Protocluster Populations with the TNG-Cluster Simulation

The Astrophysical Journal
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 protoclusters at different redshifts.

The Overdense Environments of WISE-Selected, Ultra-Luminous, High-Redshift AGN in the Submillimeter

Frontiers in Astronomy and Space Sciences, 2017
The environments around WISE-selected hot dust obscured galaxies (Hot DOGs) and WISE/radio-selected active galactic nuclei (AGNs) at average redshifts of z = 2.7 and z = 1.7, respectively, were found to have overdensities of companion Submillimeter ...

The ALMA-QUARKS Survey: Hot Molecular Cores Are a Long-standing Phenomenon in the Evolution of Massive Protostars

The Astrophysical Journal
We present an analysis of the QUARKS survey sample, focusing on protoclusters where hot molecular cores (HMCs; traced by CH _3 CN (12–11)) and HC/UC H ii regions (traced by H30 α /H40 α ) coexist.

The Bigfoot: A Footprint of a Coma Cluster Progenitor at z = 3.98

The Astrophysical Journal Letters
Protoclusters, galaxy clusters’ high-redshift progenitors, hold the key to understanding the formation and evolution of clusters and their member galaxies. However, their cosmological distances and spatial extensions (tens of Mpc) have inhibited complete

ADF22-WEB: ALMA and JWST (Sub)kiloparsec-scale Views of Dusty Star-forming Galaxies in a z ≈ 3 Protocluster

The Astrophysical Journal
We present a morphological analysis of Atacama Large Millimeter/submillimeter Array (ALMA) and James Webb Space Telescope (JWST) NIRCam images of nine dusty star-forming galaxies (DSFGs) at z _spec  ≈ 3.09, all embedded within the cosmic web filaments at
