The Bigfoot: A Footprint of a Coma Cluster Progenitor at z = 3.98

open access: yesThe Astrophysical Journal Letters
Protoclusters, galaxy clusters’ high-redshift progenitors, hold the key to understanding the formation and evolution of clusters and their member galaxies. However, their cosmological distances and spatial extensions (tens of Mpc) have inhibited complete

Dynamical Properties and Velocity Dispersion–Mass Relation of z ∼ 1 Galaxy Clusters from the GOGREEN and GCLASS Surveys

open access: yesThe Astrophysical Journal
We investigate a sample of 14 galaxy clusters from the GOGREEN and GCLASS (GG) spectroscopic data sets within the redshift range 0.87 ≤ z ≤ 1.37 and cluster masses M _200 ≳ 2 × 10 ^14 h ^−1 M _⊙ .

Observations of Galaxy Clustering at High Redshift

open access: yes, 1998
This paper reviews the current status of measurements of galaxy clustering at high redshifts (z > 0.3). The focus is on the inherent limitations in the observation and interpretation of the ``evolution of clustering''. It is likely that results from the first attempts to characterize galaxy clustering beyond the ``local'' universe have been ...

Deep Chandra Observations of the z = 1.16 Relaxed, Cool-core Galaxy Cluster SPT-CL J2215-3537

open access: yesThe Astrophysical Journal
Galaxy clusters serve as a unique and valuable laboratory for probing cosmological models and understanding astrophysics at the high-mass limit of structure formation.

Galaxy stellar mass functions of different morphological types in clusters, and their evolution between z=0.8 and z=0

open access: yes, 2010
We present the galaxy stellar mass function (MF) and its evolution in clusters from z~0.8 to the current epoch, based on the WIde-field Nearby Galaxy-cluster Survey (WINGS) (0 ...

Active Galactic Nucleus Properties of ∼1 Million Member Galaxies of Galaxy Groups and Clusters at z < 1.4 Based on the Subaru Hyper Suprime-Cam Survey

open access: yesThe Astrophysical Journal
Herein, we present the statistical properties of active galactic nuclei (AGNs) for approximately 1 million member galaxies of galaxy groups and clusters with 0.1 < cluster redshift ( z _cl ) < 1.4 selected using the Subaru Hyper Suprime-Cam, the so ...

The Future Landscape of High-Redshift Galaxy Cluster Science

open access: yes, 2019
We describe the opportunities for galaxy cluster science in the high- redshift regime where massive, virialized halos first formed and where star formation and AGN activity peaked. New observing facilities from radio to X-ray wavelengths, combining high spatial/spectral resolution with large collecting areas, are poised to uncover this population.
