Implications of multiple high-redshift galaxy clusters [PDF]

Physical 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 mass–concentration relation in massive galaxy clusters at redshift ∼1 [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
Mass and concentration of clusters of galaxies are related and evolving with redshift. We study the properties of a sample of 31 massive galaxy clusters at high redshift, 0.8 < z < 1.5, using weak and strong lensing observations. Concentration is a steep

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.

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

EPJ 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.

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

The 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

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]

EPJ Web of Conferences, 2022
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...
