Clustering of galaxies at high redshifts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
Recent observations show a large concentration of galaxies at high redshift. At first sight, strong clustering of galaxies at high redshifts seems to be in contradiction with the models of structure formation. In this paper we show that such structures are a manifestation of the strong clustering of rare peaks in the density field.

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution

open access: yesUniverse, 2022
Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

The K Band Luminosity Functions of Galaxies in High Redshift Clusters [PDF]

open access: yes, 2004
K band luminosity functions (LFs) of three, massive, high redshift clusters of galaxies are presented. The evolution of K*, the characteristic magnitude of the LF, is consistent with purely passive evolution, and a redshift of forma tion z = 1.5-2 ...

Neutral hydrogen surveys for high-redshift galaxy clusters and protoclusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We discuss the possibility of performing blind surveys to detect large-scale features of the universe using 21cm emission. Using instruments with approx. 5'-10' resolution currently in the planning stage, it should be possible to detect virialized galaxy clusters at intermediate redshifts using the combined emission from their constituent galaxies, as ...

The observed properties of high-redshift cluster galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1995
We use the semi-analytic models of galaxy formation developed by Kauffmann, White \& Guiderdoni to generate predictions for the observed properties of cluster and group galaxies at redshifts between 0 and 0.6. We examine four sets of cosmological initial conditions: low-density CDM models with and without cosmological constant, a flat CDM model and

The clustering properties of high-redshift passive galaxies

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2023
ABSTRACT We investigate the clustering properties of 3 < z < 5 candidate passive galaxies from the Merlin et al. (2019) sample residing in the GOODS-North (35 sources) and GOODS-South (33 sources) fields. Within the large uncertainties due to the paucity of sources we do not detect clustering signal in GOODS-North, while ...

Galaxy Orbits for Galaxy Clusters in Sloan Digital Sky Survey and 2dF Galaxy Redshift Survey [PDF]

open access: yes, 2007
We present the results of a study for galaxy orbits in galaxy clusters using a spectroscopic sample of galaxies in Sloan Digital Sky Survey (SDSS) and 2dF Galaxy Redshift Survey (2dFGRS).

Expectations For an Interferometric Sunyaev-Zel'dovich Effect Survey for Galaxy Clusters [PDF]

open access: yes, 2000
Non-targeted surveys for galaxy clusters using the Sunyaev-Zel'dovich effect (SZE) will yield valuable information on both cosmology and evolution of the intra-cluster medium (ICM). The redshift distribution of detected clusters will constrain cosmology,

Galaxy Clusters Selected via the Sunyaev–Zel'dovich Effect in the SPTpol 100-square-degree Survey [PDF]

open access: yes, 2020
We present a catalog of galaxy cluster candidates detected in 100 square degrees surveyed with the SPTpol receiver on the South Pole Telescope. The catalog contains 89 candidates detected with a signal-to-noise ratio greater than 4.6.
