High Redshift Galaxy Clusters as Probes of Cosmology
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.

Inkjet Printed Photonic Cellulose Nanocrystal Patterns
Patterned arrays of photonic cellulose nanocrystal microfilms are prepared by inkjet printing. By dispensing directly through an oil layer, the printing and drying processes can be decoupled, which avoids the coffee stain effect and enables complex arrays to be produced.

Forecasting the Fast Radio Burst Population Observed through Galaxy Cluster Lenses
High-redshift fast radio bursts (FRBs) are expected to be extremely powerful probes of our Universe. However, while a significant number of FRBs are expected to exist at high redshift, detecting them has been difficult, with only a handful robustly ...

The Evolution of the Galaxy Cluster Luminosity-Temperature Relation
We analyzed the luminosity-temperature (L-T) relation for 2 samples of galaxy clusters which have all been observed by the ASCA satellite.

Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies
Galaxies in the early Universe appear to have grown too big too fast, assembling into massive, monolithic objects more rapidly than anticipated in the hierarchical Lambda cold dark matter (ΛCDM) structure formation paradigm.

Observations of Galaxy Clustering at High Redshift
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 ...

Identification of High-redshift Galaxy Overdensities in GOODS-N and GOODS-S
We conduct a systematic search for high-redshift galaxy overdensities at 4.9 < z _spec < 8.9 in both the Great Observatories Origins Deep Survey (GOODS)-N and GOODS-S fields using James Webb Space Telescope/Near-Infrared Camera (JWST/NIRCam) imaging from

We report the discovery of an extreme galaxy overdensity at z = 5.4 in the GOODS-S field using James Webb Space Telescope (JWST)/NIRCam imaging from JADES and JEMS alongside JWST/NIRCam wide-field slitless spectroscopy from FRESCO.

The Search for AGN in Distant Galaxy Clusters
We are undertaking the first systematic study of the prevalence of AGN activity in a large sample of high redshift galaxy clusters. Local clusters contain mainly red elliptical galaxies, and have little or no luminous AGN activity.
