A New Stellar Mass Proxy for Subhalo Abundance Matching
The Astrophysical Journal, 2023 Subhalo abundance matching (SHAM) has played an important role in improving our understanding of how galaxies populate their host dark matter halos.

Red Halos of Galaxies – Reservoirs of Baryonic Dark Matter? [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractDeep optical/near-IR surface photometry of galaxies outside the Local Group have revealed faint and very red halos around objects as diverse as disk galaxies and starbursting dwarf galaxies. The colours of these structures are too extreme to be reconciled with stellar populations similar to those seen in the stellar halos of the Milky Way or ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields
Advanced Science, EarlyView.Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Properties of Galaxy Dark Matter Halos from Weak Lensing [PDF]
The Astrophysical Journal, 2004 We present the results of a study of the average mass profile around galaxies using weak gravitational lensing. We use 45.5 deg2 of RC band imaging data from the Red-Sequence Cluster Survey (RCS) and define a sample of ~ 1.2 × 105 lenses with 19.5 < RC < 21, and a sample of ~ 1.5 × 106 background galaxies with 21.5 < R < 24.We constrain the

Advanced Science, EarlyView.A microneedle spoilage sensor for packaged food products is presented. The sensor is composed entirely of food‐derived agents, integrated together using a novel material processing approach. This resultant platform nondestructively reports spoilage state in real‐time through a colorimetric output.

Self-similar Decomposition of the Hierarchical Merger Tree of Dark Matter Halos
The Astrophysical JournalIn the ΛCDM universe, structure formation is generally not a self-similar process, while some self-similarity remains in certain statistics, which can greatly simplify our description and understanding of the cosmic structures. In this work, we show that

The Astrophysical Journal, 2023 The radial acceleration relation (RAR) represents a tight empirical relation between the inferred total and baryonic centripetal accelerations, g _tot = GM _tot (< r )/ r ^2 and g _bar = GM _bar (< r )/ r ^2 , observed in galaxies and galaxy clusters ...

The Structure of Dark Matter Halos in Dwarf Galaxies [PDF]
The Astrophysical Journal, 1995 Some dwarf galaxies have HI rotation curves that are completely dominated by a surrounding dark matter (DM) halo (e.g. Carignan & Freeman 1988). These objects represent ideal candidates for an investigation of the density structure of low-mass DM halos as the uncertainties resulting from the subtraction of the visible component are small, even in ...

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides
Advanced Science, EarlyView.This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...
