Cluster versus Field: Clear Evidence for a Morphology–Density Relation in All Environments at z ∼ 1.6

The Astrophysical Journal
We explore the relationship between galaxy structure, stellar mass, and local galaxy density in three SpARCS clusters at z  ∼ 1.6 and compare with field galaxies from the 3D-HST survey.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

A Catalog of 1.58 Million Clusters of Galaxies Identified from the DESI Legacy Imaging Surveys

The Astrophysical Journal Supplement Series
Based on the DESI Legacy Imaging Surveys released data and available spectroscopic redshifts, we identify 1.58 million clusters of galaxies by searching for the overdensity of the stellar mass distribution of galaxies within redshift slices around ...

Galaxy assembly revealed by globular clusters

The Open Journal of Astrophysics
Many observable properties of globular clusters (GCs) provide valuable insights for unveiling the hierarchical assembly of their host galaxy. For the Milky Way (MW) in particular, GCs from different accreted satellite galaxies show distinct chemical ...

Galaxy subgroups in galaxy clusters

, 2011
Galaxies which fall into clusters as part of the same infall halo can retain correlations due to their shared origin. N-body simulations are used to study properties of such galaxy subgroups within clusters, including their richnesses and prevalence.
