The Astrophysical JournalWe investigate when and how the relations of galaxy morphology and star-forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy clusters with total mass ${{M}}_{\mathrm{tot}}^{\mathrm{cl}}\gt 5\times {10}^{13}

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, EarlyView.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Fortschritte der Physik, EarlyView.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

A Protocluster of Massive Quiescent Galaxies at z = 4
The Astrophysical JournalWe report on discovery of a concentration of massive quiescent galaxies located at z = 4. The concentration is first identified using high-quality photometric redshifts based on deep, multiband data in Subaru/XMM-Newton Deep Field.

Small, EarlyView.Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...
