Water Environment Research, Volume 98, Issue 9, September 2026.Metagenomics revealed distinct anthropogenic signatures in the microbiome of freshwater sources on Marambaia Island, supported by the Anthropogenic Impact Index (AII). Impacted sites showed lower microbial diversity, enrichment of fecal‐associated taxa, and 14 antimicrobial resistance genes, whereas conductivity, salinity, and turbidity explained 88.1%

A Splashback-like Feature of Central Galaxies in Galaxy Clusters
The Astrophysical JournalWe investigate a splashback-like feature in the outer region of central galaxies (CGs) in clusters. This feature is detected as a “dip” in the radial slope of the CG surface brightness, derived through the stacking of Dark Energy Survey data of over 4000

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum
Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

The Astronomical JournalWe investigate the connection between stellar mass distribution, assembly history, and star formation timescales in low-redshift massive early-type galaxies (ETGs) by combining deep LegacySurvey imaging with MaNGA’s spatially resolved spectroscopy ...

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Polygon‐Based Spectral Reflectance Sampling for Real‐Time River Discharge Estimation
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract River discharge estimation (RDE) methods are traditionally prone to high costs, vulnerability to extreme events, and are constrained by real‐time data availability. Current remote sensing‐based RDE approaches mainly extract basic river features such as width and water surface elevation, but rarely exploit the full spectral information from ...

Stellar halos of bright central galaxies
Aims. We present theoretical predictions and extrapolations from observed data of the stellar halos surrounding central group and cluster galaxies, and the transition radius between them and the intracluster or diffuse light. Methods.

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Spatially resolved spectroscopy of faint star-forming galaxies & their environments in the high redshift universe [PDF]
, 2011 This thesis is concerned with the spectroscopic observations of distant galaxies, 1 < z < 5. The galaxies presented here are intrinsically faint such that their ux is dominated by ordinary star formation rather than galaxy-galaxy merging and/or ...
