Cluster mass calibration at high redshift: HST weak lensing analysis of 13 distant galaxy clusters from the South Pole Telescope Sunyaev–Zel'dovich Survey [PDF]

open access: bronze, 2017
We present an HST/Advanced Camera for Surveys (ACS) weak gravitational lensing analysis of 13 massive high-redshift (zmedian = 0.88) galaxy clusters discovered in the South Pole Telescope (SPT) Sunyaev–Zel'dovich Survey.

Submillimetre source counts in the fields of high-redshift galaxy clusters [PDF]

open access: bronze, 2011
We present a submillimetre survey of seven high-redshift galaxy clusters (0.64 < z < 1.0) using the Submillimetre Common-User Bolometer Array (SCUBA) at 850 and 450 m.

Modelling galaxy clustering at high redshift [PDF]

open access: yesMonthly 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 ...

Molecular gas in the halo fuels the growth of a massive cluster galaxy at high redshift [PDF]

open access: greenScience, 2016
The massive Spiderweb galaxy is surrounded by molecular gas as it goes through its formation process. A massive galaxy forming from molecular gas The most massive galaxies gather their stars by merging with smaller galaxies and by accreting gas, which is

The accelerated build-up of the red sequence in high-redshift galaxy clusters [PDF]

open access: yes, 2016
We analyse the evolution of the red sequence in a sample of galaxy clusters at redshifts $0.8 11.5$) red sequence galaxies in the WINGS clusters, which do not include only the brightest cluster galaxies and which are not present in the HCS clusters ...

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

open access: yesThe 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.

HIROCS – a galaxy cluster survey at high redshifts [PDF]

open access: yesProceedings of the International Astronomical Union, 2004
As a step towards our understanding of galaxy evolution and for testing predictions of cosmological models we started a survey for galaxy clusters intending to identify candidates out to redshifts of ~1.5: HIROCS (= Heidelberg InfraRed/Optical Cluster Survey) is a multi-color survey (B, R, i, z and H) covering 11 square degrees in four fields on the ...

Optical Identifications of High-Redshift Galaxy Clusters from the Planck Sunyaev–Zeldovich Survey [PDF]

open access: yes, 2018
We present the results of optical identifications and spectroscopic redshift measurements for galaxy clusters from the second Planck catalogue of Sunyaev–Zeldovich sources (PSZ2) located at high redshifts, z ≈ 0.7−0.9.

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

open access: yesThe 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.
