Inkjet Printed Photonic Cellulose Nanocrystal Patterns

open access: yesAdvanced Materials, Volume 36, Issue 1, January 4, 2024.
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.

The Manhattan Suite: Accelerated Galaxy Evolution in the Early Universe

open access: yesThe Astrophysical Journal
Observational advances have allowed the detection of galaxies, protoclusters, and galaxy clusters at higher and higher redshifts, opening a new view into extreme galaxy evolution.

COSMOS2020: Discovery of a Protocluster of Massive Quiescent Galaxies at z = 2.77

open access: yesThe Astrophysical Journal Letters, 2023
Protoclusters of galaxies have been found in the last quarter-century. However, most of them have been found through the overdensity of star-forming galaxies, and there have been no known structures identified by more than two spectroscopically confirmed

Constraining galaxy cluster temperatures and redshifts with eROSITA survey data [PDF]

open access: yes, 2014
The nature of dark energy is imprinted in the large-scale structure of the Universe and thus in the mass and redshift distribution of galaxy clusters. The upcoming eROSITA mission will exploit this method of probing dark energy by detecting roughly 100 ...

Forecasting the Fast Radio Burst Population Observed through Galaxy Cluster Lenses

open access: yesThe Astrophysical Journal
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 ...

Resolving Globular Cluster Formation within a Cosmological Context [PDF]

open access: yes, 2009
We place constraints on the formation redshifts for blue globular clusters (BGCs), independent of the details of hydrodynamics and population III star formation.

Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies

open access: yesThe Astrophysical Journal
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.

Identification of High-redshift Galaxy Overdensities in GOODS-N and GOODS-S

open access: yesThe Astrophysical Journal
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
