Statistical Characteristics of Electron Precipitation During HSS‐ and ICME‐Driven Storms Observed by the EISCAT Radar

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The 1–100 keV electron precipitation during storm time has been studied by applying the updated ELSPEC inversion method to field‐aligned electron density profiles measured by the EISCAT Tromsø radar at L = 6.5. The statistical properties of peak energy, total energy flux, and total number flux as a function of MLT have been studied for the two

Investigating Long-Term Behaviour of X-ray Binaries Using Archival Data

Acta Polytechnica CTU Proceedings, 2015
Long term modulations have been detected in a wide variety of both low and high-mass X-ray binaries. The All Sky Monitor on board the Rossi X-ray Timing Explorer provides the most extensive (~15 years) and sensitive X-ray archive for studying such ...

Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Poleward Disturbances in Thermospheric Winds During the 3–4 November 2021 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract This study focuses on ionosphere‐thermosphere coupling over North America during the 3–4 November 2021 strong geomagnetic storm (Kp 8−). We comprehensively analyze storm‐time ionospheric and thermospheric disturbances using data from ground‐based instruments at Poker Flat, Millstone Hill, and Urbana, as well as satellite observations and model

Search for double beta decay of 136Xe to the 0 1 + $$ {0}_1^{+} $$ excited state of 136Ba with PandaX-4T

Journal of High Energy Physics
We perform a search of double beta decay of 136Xe to the excited state, 0 1 + $$ {0}_1^{+} $$ , of 136Ba (2νββ- 0 1 + $$ {0}_1^{+} $$ ), using the dual-phase xenon detector of PandaX-4T with the first 94.9-day commissioning data.
