Implications of multiple high-redshift galaxy clusters [PDF]

open access: yesPhysical Review D, 2011
To date, 14 high-redshift (z>1.0) galaxy clusters with mass measurements have been observed, spectroscopically confirmed and are reported in the literature. These objects should be exceedingly rare in the standard LCDM model.

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.

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

open access: yesThe 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 =

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

open access: yes, 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.

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.

Distant Galaxy Clusters Identified From Optical Background Fluctuations [PDF]

open access: yes, 1996
We present the first high redshift (0.3 < z < 1.1) galaxy clusters found by systematically identifying optical low surface brightness fluctuations in the background sky.

The build-up of the colour-magnitude relation in galaxy clusters since z~0.8 [PDF]

open access: yes, 2006
Using galaxy clusters from the ESO Distant Cluster Survey, we study how the distribution of galaxies along the colour-magnitude relation has evolved since z~0.8.

The Three Hundred–NIKA2 Sunyaev–Zeldovich Large Program twin samples: Synthetic clusters to support real observations [PDF]

open access: yesEPJ Web of Conferences, 2022
The simulation database of The Three Hundred Project has been used to pick synthetic clusters of galaxies with properties close to the observational targets of the NIKA2 camera Sunyaev–Zeldovich (SZ) Large Program.

Cluster detection from surface-brightness fluctuations in SDSS data [PDF]

open access: yes, 2001
Galaxy clusters can be detected as surface brightness enhancements in smoothed optical surveys. This method does not require individual galaxies to be identifiable, and enables clusters to be detected out to surprisingly high redshifts, as recently ...

A Gradual Decline of Star Formation since Cluster Infall: New Kinematic Insights into Environmental Quenching at 0.3 < z < 1.1

open access: yesThe Astrophysical Journal, 2023
The environments where galaxies reside crucially shape their star formation histories. We investigate a large sample of 1626 cluster galaxies located within 105 galaxy clusters spanning a large range in redshift (0.26 < z < 1.13). The galaxy clusters are
