TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

open access: yesRadio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Solar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun to the near‐Earth space.

Comparative Analysis of Ionospheric Responses to Ultra‐Fast Kelvin Waves With Wavenumbers 1, 2, and 3

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract We employed zonal wind data from Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics Doppler Interferometer, equatorial electrojet (EEJ) measurements from Jicamarca (12°S, 77°W), and global ionospheric total electron content (TEC) maps to investigate the effects of ultra‐fast Kelvin waves (UFKW) with zonal wavenumbers 2 and 3 ...

Neural Networks for Space Debris Classification

open access: yesExpert Systems, Volume 43, Issue 1, January 2026.
ABSTRACT Significant research in the field of space domain awareness (SDA) has focused on improving AI‐driven data processing and classification tasks. Previous studies have explored the classification of orbiting man‐made object types such as satellites, rocket bodies, and debris, yet there is a noticeable gap in the literature concerning the ...
