The AIDA-TNG project: 3D halo shapes
Astronomy & AstrophysicsContext. The shapes of dark matter halos can be used to constrain the fundamental properties of dark matter. In standard cold dark matter (CDM) cosmologies, halos are typically triaxial, with a preference for prolate configurations; however, including ...

Halo Properties from Observable Measures of Environment: I. Halo and Subhalo Masses
The Open Journal of Astrophysics, 2023 The stellar mass - halo mass relation provides a strong basis for connecting galaxies to their host dark matter halos in both simulations and observations.

Meteoritics &Planetary Science, EarlyView.Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

Closing the Gap between Observed Low-mass Galaxy H i Kinematics and Cold Dark Matter Predictions
The Astrophysical JournalTesting the standard cosmological model (ΛCDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models by linking observational properties of galaxies at small scales (low mass ...

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.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, EarlyView.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 ...

Shaping the Milky Way: The Interplay of Mergers and Cosmic Filaments
The Astrophysical JournalThe large-scale morphology of Milky Way (MW)–mass dark matter halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive satellites.

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis
Plant, Cell &Environment, EarlyView.ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
