Flexible, Photonic Films of Surfactant‐Functionalized Cellulose Nanocrystals for Pressure and Humidity Sensing

Small Structures, Volume 5, Issue 7, July 2024.
Cellulose nanocrystals are abundant, biodegradable nanoparticles that can self‐assemble into a helical stacking that exhibits structural color. By adding a single surfactant, cellulose nanocrystals can be made compatible with apolar solvents, which are widely used for industrial coatings.

What is a Cool-Core Cluster? A Detailed Analysis of the Cores of the X-ray Flux-Limited HIFLUGCS Cluster Sample

, 2009
We use the largest complete sample of 64 galaxy clusters (HIghest X-ray FLUx Galaxy Cluster Sample) with available high-quality X-ray data from Chandra, and apply 16 cool-core diagnostics to them, some of them new. We also correlate optical properties of

Stellar populations and evolution of early-type cluster galaxies: Constraints from optical imaging and spectroscopy of z=0.5-0.9 galaxy clusters [PDF]

, 2013
We present an analysis of stellar populations and evolutionary history of galaxies in three similarly rich galaxy clusters MS0451.6-0305 (z=0.54), RXJ0152.7-1357 (z=0.83), and RXJ1226.9+3332 (z=0.89); based on high S/N ground-based optical spectroscopy ...

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics

Annalen der Physik, Volume 536, Issue 2, February 2024.
Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

JWST and ALMA Joint Analysis with [O II] λλ3726, 3729, [O III] λ4363, [O III] 88 μm, and [O III] 52 μm: Multizone Evolution of Electron Densities at z ∼ 0–14 and its Impact on Metallicity Measurements

The Astrophysical Journal
We present a JWST and Atacama Large Millimeter/submillimeter Array (ALMA) detailed study of the interstellar medium properties of high-redshift galaxies.

Measuring Galaxy Environments with Deep Redshift Surveys

, 2005
We study the applicability of several galaxy environment measures (n^th-nearest-neighbor distance, counts in an aperture, and Voronoi volume) within deep redshift surveys.

Cosmology with Gravitational Waves: A Review

Annalen der Physik, Volume 536, Issue 2, February 2024.
The review gives an overview of the most recent advances in gravitational‐wave (GWs) cosmology. After an in‐depth discussion of methodologies and tools for GW cosmology, it presents the latest results on measurements of standard cosmological parameters from the LIGO, Virgo, and KAGRA detections.

Selecting Clusters and Protoclusters via Stellar Mass Density. I. Method and Tests on Mock HSC-SSP Catalogs

The Astrophysical Journal
We present an algorithm designed to identify galaxy (proto)clusters in wide-area photometric surveys by first selecting their dominant galaxy—i.e., the brightest cluster galaxy (BCG) or protoBCG—through the local stellar mass density traced by massive ...

Galaxy clusters discovered with a Sunyaev-Zel'dovich effect survey

, 2009
The South Pole Telescope (SPT) is conducting a Sunyaev-Zel'dovich (SZ) effect survey over large areas of the southern sky, searching for massive galaxy clusters to high redshift.
