The ROSAT-ESO Flux Limited X-ray Galaxy Cluster Survey (REFLEX II) I. Newly identified X-ray luminous clusters at z>=0.2

, 2011
We report 19 intermediate redshift clusters newly detected in the ROSAT All-Sky survey that are spectroscopically confirmed. They form a part of 911 objects in the REFLEX II cluster catalogue with a limiting flux of 1.8\times10^12 erg/s/cm2 in the 0.1-2 ...

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.

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.

Inkjet Printed Photonic Cellulose Nanocrystal Patterns

Advanced 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.

Testing Cosmology with Extreme Galaxy Clusters [PDF]

, 2012
Motivated by recent suggestions that a number of observed galaxy clusters have masses which are too high for their given redshift to occur naturally in a standard model cosmology, we use Extreme Value Statistics to construct confidence regions in the ...

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.

Completeness in Photometric and Spectroscopic Searches for Clusters [PDF]

, 2001
We investigate, using simulated galaxy catalogues, the completeness of searches for massive clusters of galaxies in redshift surveys or imaging surveys with photometric redshift estimates, i.e. what fraction of clusters (M>10^14/h Msun) are found in such
