The Thickness of Galaxy Disks from z = 5 to 0 Probed by JWST
The Astrophysical Journal LettersAlthough a thick disk is a structure prevalent in local disk galaxies and also present in our home Galaxy, its formation and evolution are still unclear.

The Tully-Fisher Zero Point Problem
, 2008 A long standing problem for hierarchical disk galaxy formation models has been the simultaneous matching of the zero point of the Tully-Fisher relation and the galaxy luminosity function (LF).

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 ...

Different Influence of Gas Accretion on the Evolution of Star-forming and Non-star-forming Galaxies
The Astrophysical JournalUsing integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we investigate the spatially resolved properties and empirical relations of a star-forming galaxy and a non-star-forming galaxy hosting ...

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 ...

Starburst Galaxies in Their Last Billion Years: An Hδ Absorption Line Selected Sample
The Astrophysical JournalIn this paper, we focus on the study of starburst galaxies in their final billion years. Our galaxy selection is based solely on the presence of the H δ absorption line, which permits the later evolution of starburst galaxies to be traced, coinciding ...

Small Methods, EarlyView.This study reports a parylene–plasma–porous (PPP) treatment that directionally transforms conventional porous membranes into dual‐gradient Janus structures. By aligning porosity and wettability gradients through asymmetric chemical‐vapor‐deposition (CVD) and localized O2 plasma treatment, the resulting membrane enables gravity‐independent self‐pumping ...
