Galaxy Clusters and Large Scale Structure at High Redshifts [PDF]

, 1998
We present a detailed study of a rich galaxy cluster at z=2.38. We demonstrate that this cluster contains large overdensities of damped Ly-alpha absorption lines, of Ly-alpha emitting galaxies and of extremely red objects. The overdensity of extremely red objects in this field demonstrates that many are high z galaxies.

The association of galaxy clusters with moderately-high-redshift quasars [PDF]

Symposium - International Astronomical Union, 1986
CCD images of quasars having redshifts between 0.3 and 0.65 are analyzed to study the association of galaxies with quasars. Average luminosity functions (LF) of the excess galaxies associated with the radio-loud quasars are determined. It is found that for the sub-sample with z>0.55, there is a significant brightening of the characteristic magnitude

Modelling galaxy clustering at high redshift [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
We discuss the theoretical interpretation of observational data concerning the clustering of galaxies at high redshifts. Building on the theoretical machinery developed by Matarrese et al. (1997), we make detailed quantitative predictions of galaxy clustering statistics for a variety of cosmological models, taking into account differences in spatial ...

The JWST PEARLS View of the El Gordo Galaxy Cluster and of the Structure It Magnifies

The Astrophysical Journal, 2023
The massive galaxy cluster El Gordo ( z = 0.87) imprints multitudes of gravitationally lensed arcs onto James Webb Space Telescope Near-Infrared Camera (NIRCam) images.

ODIN: Where Do Lyα Blobs Live? Contextualizing Blob Environments within Large-scale Structure

The Astrophysical Journal, 2023
While many Ly α blobs (LABs) are found in and around several well-known protoclusters at high redshift, how they trace the underlying large-scale structure is still poorly understood. In this work, we utilize 5352 Ly α emitters (LAEs) and 129 LABs at z =

Accelerated Structural Evolution of Galaxies in a Starbursting Cluster at z = 2.51

The Astrophysical Journal Letters, 2023
Structural properties of cluster galaxies during their peak formation epoch, z ∼ 2–4 provide key information on whether and how the environment affects galaxy formation and evolution.

RELICS: The Reionization Lensing Cluster Survey and the Brightest High-z Galaxies [PDF]

, 2020
Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy populations.

New spectroscopic confirmations of high-redshift galaxy clusters [PDF]

Astronomy & Astrophysics, 2005
We present new spectroscopic data in the field of five high-redshift (z>=0.6) candidate galaxy clusters, drawn from the EIS Cluster Candidate Catalog. A total of 327 spectra were obtained using FORS1 at the VLT, out of which 266 are galaxies with secure redshifts.

Hawaii Two-0: high-redshift galaxy clustering and bias [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We perform an analysis of two-point galaxy clustering and galaxy bias using Subaru Hyper-Suprime Cam (HSC) data taken jointly by the Subaru Strategic Program and the University of Hawaii in the Cosmic Evolution Survey (COSMOS) field over an area of 1.8 sq deg.
