Near‐Earth Solar Wind Speed of Fast Coronal Mass Ejections
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Using solar wind and ground magnetometer data for solar cycles 23–25, extreme‐value power‐law models are developed that quantify relationships between near‐Earth solar wind speed and Sun‐to‐Earth transit times of interplanetary coronal mass ejections (ICMEs).

Observational implications of cosmologically coupled black holes
The Open Journal of Astrophysics, 2023 It was recently suggested that "cosmologically coupled" black holes with masses that increase in proportion to the volume of the Universe might constitute the physical basis of dark energy.

Predicting Geomagnetic Activity in the Ascending and Declining Phases of the Solar Cycle
Space Weather, Volume 24, Issue 8, August 2026.Abstract Most predictions of space climate, that is, the long‐term behavior of the solar‐terrestrial environment, have focused on forecasting the 11‐year sunspot cycle. Geomagnetic activity, on the other hand, has mainly been predicted in shorter, space weather timescales of up to days to weeks.

Physics Letters B, 2019 We report about the possibility for interacting Kerr sources to exist in two different states – black holes or naked singularities – both states characterized by the same masses and angular momenta.

Space Weather, Volume 24, Issue 8, August 2026.Abstract We present the first real‐time predictions of coronal mass ejection (CME) magnetic structure and resulting geomagnetic impact at Earth for two events using far‐upstream observations from Solar Orbiter during March 2024. While our approach assumes idealized conditions for CME propagation and scaling, in situ magnetic field data from upstream ...

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1847-1860, August 2026.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1965-1993, August 2026.Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Interpretable Machine Learning for Finding Intermediate-mass Black Holes
The Astrophysical JournalDefinitive evidence that globular clusters (GCs) host intermediate-mass black holes (IMBHs) is elusive. Machine-learning (ML) models trained on GC simulations can in principle predict IMBH host candidates based on observable features.

Advanced Materials Interfaces, Volume 13, Issue 14, 21 July 2026.A triple‐cation perovskite detector with a quasi‐interdigitated back‐contact architecture enables highly sensitive and linear EUV/soft x‐ray detection by minimizing electrode shadowing and enhancing charge extraction. Efficient interfacial carrier collection and rapid temporal response highlight the potential of back‐contact‐engineered perovskites for ...
