SciPost Physics Proceedings, 2023 After more than a decade since its discovery, the Galactic center gamma-ray excess - discovered with the Fermi Large Area Telescope - remains puzzling. While the spectrum of the signal can be explained by either dark matter or an unresolved population of

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.A new species Astragalus zhobensis, from Qamardin Karez, Zhob district, northern Balochistan, Pakistan is described and illustrated. The new species is morphologically similar to A. cartilagineus, but can be distinguished by strigose hairs 3–5 mm long, (not stiff 1.5−4.0 mm long hairs); stipules 5–15 mm (not 8−12 mm) long; leaflets in 4–6 pairs, (not 3–

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
AGU Advances, Volume 6, Issue 6, December 2025.Abstract With its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole of Venus has been expected to separate from the figure pole in response to mantle flow ...

Thermal Reactions of Smectite Minerals at Earthquake Timescales
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.Abstract Frictional heating causes a transient temperature rise in fault zones during earthquakes that leads to metamorphic reactions within the fault rocks. The products of these reactions provide potential evidence of earthquakes in both the outcrop and drill core. Clay minerals such as smectites are commonly found in faults.

Gauging the Helium Abundance of the Galactic Bulge RR Lyrae Stars [PDF]
, 2018 We report the first estimate of the He abundance of the population of RR Lyrae stars in the Galactic bulge. This is done by comparing the recent observational data with the latest models.

Orbits of Selected Globular Clusters in the Galactic Bulge [PDF]
Publications Astronomical Society of Australia, 2018 We present orbit analysis for a sample of eight inner bulge globular clusters, together with one reference halo object. We used proper motion values derived from long time base CCD data.
