Before its time: A remarkably evolved protocluster core at z = 7.88

Astronomy & Astrophysics
Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed by large gas reservoirs.

The environments of high-redshift radio galaxies and quasars: probes of protoclusters [PDF]

, 2016
We use the GALFORM semi-analytical model to study high-density regions traced by radio galaxies and quasars at high redshifts. We explore the impact that baryonic physics has upon the properties of galaxies in these environments.

The HST-Hyperion Survey: Grism Observations of a z ∼ 2.5 Protosupercluster

The Astrophysical Journal
We present the 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 regions of the Hyperion protosupercluster at z  ∼ 2.45, which are ...

ALMA High-resolution Spectral Survey of Thioformaldehyde (H2CS) toward Massive Protoclusters

The Astrophysical Journal
Investigating the temperature and density structures of gas in massive protoclusters is crucial for understanding the chemical properties therein. In this study, we present observations of the continuum and thioformaldehyde (H _2 CS) lines at 345 GHz of ...

Planck far-infrared detection of hyper suprime-cam protoclusters at z similar to 4: Hidden AGN and star formation activity [PDF]

, 2019
We perform a stacking analysis of Planck, AKARI, Infrared Astronomical Satellite, Wide-field Infrared Survey Explorer, and Herschel images of the largest number of (candidate) protoclusters at z ~ 3.8 selected from the Hyper Suprime-Cam Subaru Strategic ...

From Protoclusters to Clusters: The Role of Large-Scale Structure in Galaxy Evolution [PDF]

This thesis explores the impact of environment on galaxy evolution at high redshift, focusing on the role of environmental quenching in clusters and protoclusters. By combining deep observational data from multiple surveys with statistical analyses, this

Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at z = 7.66

Astronomy & Astrophysics
The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spectroscopy of the photometrically identified z = 7.66 protocluster core in ...
