Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.

The ERA Method with Idealizing PSF for Precise Weak Gravitational Lensing Shear Analysis
, 2015 We generalize ERA method of PSF correction for more realistic situations. The method re-smears the observed galaxy image(galaxy image smeared by PSF) and PSF image by an appropriate function called Re-Smearing Function(RSF) to make new images which have the same ellipticity with the lensed (before smeared by PSF) galaxy image.

Gravitational Lensing by Vector Perturbations [PDF]
, 2022 Perturbation theory is a useful tool used in cosmology to describe fluctuations in an almost-uniform universe. We focus on vector-type perturbations, and investigate their gravitational lensing effects.

The Effect of Intrinsic Alignments on Weak-lensing Statistics in Hydrodynamical Simulations
The Astrophysical JournalThe next generation of weak-gravitational-lensing surveys has the potential to place stringent constraints on cosmological parameters. However, their analysis is limited by systematics such as the intrinsic alignments of galaxies, which alter weak ...

The cosmology dependence of the cluster weak-lensing mass bias
Astronomy & AstrophysicsContext. Measurements of the shear induced by weak gravitational lensing around galaxy cluster lines of sight are the gold standard for calibrating cluster observable–mass relations, enabling a robust and precise inference of cosmological parameters. The

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Journal of Texture Studies, Volume 57, Issue 5, October 2026.Starch functions as a key hydrocolloid shaping texture and stability in the formulation engineering of sweet foods. Sugar‐starch hydration interactions control gelatinization and rheological behavior. Modified starches enhance tolerance to heat, shear, acidity, and low moisture, and starch‐hydrocolloid blends enable tailored textures and improved shelf
