The Astrophysical Journal, 2023 Based on independent shear measurements using the Dark Energy Camera Legacy Survey/DR8 imaging data, we measure the weak lensing signals around isolated central galaxies (ICGs) from Sloan Digital Sky Survey/DR7 at z ∼ 0.1.

Sedimentology, EarlyView.ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

THE SYSTEMATIC ERROR TEST FOR PSF CORRECTION IN WEAK GRAVITATIONAL LENSING SHEAR MEASUREMENT BY THE ERA METHOD BY IDEALIZING PSF [PDF]
The Astrophysical Journal, 2016 ABSTRACT We improve the ellipticity of re-smeared artificial image (ERA) method of point-spread function (PSF) correction in a weak lensing shear analysis in order to treat the realistic shape of galaxies and the PSF. This is done by re-smearing the PSF and the observed galaxy image using a re-smearing function (RSF) and allows us to use

Microlensing search for extra solar planets [PDF]
, 2015 Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

The Astrophysical JournalWe present a novel, model-independent technique for fitting the cross-component of weak lensing shear, γ _× , along a line of sight by combining kinematic and photometric measurements of a single lensed galaxy.

Preservation of Isolated Vesicles in Submarine Pumice and Implications for Submarine Slope Stability
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Pumice clasts from submarine eruptions contain abundant isolated vesicles that are completely encased in glass. As erupted clasts cool, gas inside isolated vesicles contracts, leading to low pressures inside those vesicles. Despite low pressures, isolated vesicles can be preserved in submarine pumice deposits to water depths of approximately 1–

Preliminary Evidence for Lensing-induced Alignments of High-redshift Galaxies in JWST-CEERS
The Astrophysical JournalThe majority of low-mass ( ${\mathrm{log}}_{10}{M}_{* }/{M}_{\odot }=9\mbox{--}10$ ) galaxies at high redshift ( z > 1) appear elongated in projection. We use JWST-CEERS observations to explore the role of gravitational lensing in this puzzle.

Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers
Advanced Science, Volume 13, Issue 55, 5 October 2026.This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Ellipticities of Galaxy Cluster Halos from Halo–Shear–Shear Correlations
The Astrophysical JournalWe report the first detection of the halo ellipticities of galaxy clusters by applying the halo–shear–shear correlations (HSSCs), without the necessity of using major axis determination.
