On the Gas Surrounding High-Redshift Galaxy Clusters [PDF]
Publications of the Astronomical Society of Australia, 2001 Francis & Hewett (1993) identified two 10-Mpc scale regions of the high redshift universe that were seemingly very overdense in neutral hydrogen. Subsequent observations showed that at least one of these gas-rich regions enveloped a cluster of galaxies ...

High redshift X-ray galaxy clusters [PDF]
SPIE Newsroom, 2007 In this paper we re-visit the observational relation between X-ray luminosity and temperature for high-z galaxy clusters and compare it with the local L_X-T and with theoretical models. To these ends we use a sample of 17 clusters extracted from the Chandra archive supplemented with additional clusters from the literature, either observed by Chandra or

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.

Galaxy Merger Candidates in High-redshift Cluster Environments [PDF]
The Astrophysical Journal, 2017 Abstract We compile a sample of spectroscopically and photometrically selected cluster galaxies from four high-redshift galaxy clusters ( ) from the Spitzer Adaptation of the Red-Sequence Cluster Survey (SpARCS), and a comparison field sample selected from the UKIDSS Deep ...

Clustering analysis of high-redshift luminous red galaxies in Stripe 82 [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We present a clustering analysis of Luminous Red Galaxies in SDSS Stripe 82. We study the angular 2-point correlation function, of 130,000 LRG candidates via colour-cut selections in izK with the K band coverage coming from UKIDSS LAS. We have used the cross-correlation technique of Newman (2008) to establish the LRG redshift distribution.

Methods for identifying high‐redshift galaxy cluster candidates [PDF]
Astronomische Nachrichten, 2019 AbstractRecent theories linked long gamma ray bursts (GRBs) to galaxies with rapid star formation or starburst; thus, we expect that long GRBs (LGRBs) are more frequent in midcluster galaxies where mergers and tidal interactions between gas‐rich galaxies are more likely to occur. Yet there is no galaxy cluster known to be associated with LGRBs.

High Redshift Galaxy Clusters as Probes of Cosmology [PDF]
, 2001 A few, simple and qualitative examples of the potential of galaxy clusters as diagnostics of cosmology are presented. In relation to these we discuss briefly three ongoing or forthcoming cluster surveys in the optical/NIR, X-rays and the cosmic microwave radiation background.
