The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat Experiment

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Daily Atmospheric Ionospheric Limb Imager (DAILI) (Daily Atmospheric and Ionospheric Limb Imager) mission utilized a 6U CubeSat, deployed at about 410 km altitude in a 51‐degree orbit, to make simultaneous daytime limb measurements in two colors; at 630 nm to measure the OI (630 nm) redline and at 765 nm to measure the O2 ${\mathrm{O}}_{2}$

Medium‐Scale Traveling Ionospheric Disturbances Induced by Secondary Gravity Waves Associated With Record‐Breaking Heavy Rainfall in August 2021 Over Kyushu, Japan

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract This study reconstructs a multistep gravity wave (GW) pathway, from the generation of primary GWs by deep convection in the troposphere to the generation of secondary GWs that drive semi‐concentric medium‐scale traveling ionospheric disturbances (MSTIDs) in the ionosphere, during the record‐breaking heavy rainfall over Kyushu, Japan, in August

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

open access: yesJournal 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.

Obtaining Local‐Tie Vectors From Short‐Baseline Interferometry Between Legacy S/X and VGOS Telescopes at Ny‐Ålesund

open access: yesRadio Science, Volume 61, Issue 9, September 2026.
Abstract With the ongoing transition for geodetic Very Long Baseline Interferometry (VLBI) from the use of legacy S/X telescopes to the VLBI Global Observing System (VGOS), it is necessary to connect the new VGOS network to the existing legacy S/X telescopes.

Correlation of High‐Latitude Scintillation With Auroral Precipitation: Case Studies Using GNSS Radio Occultation Data From PlanetiQ

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting scintillation events.

Very high energy gamma ray astronomy and non pulsating low mass x-ray binaries [PDF]

open access: yes, 1991
This thesis is concerned with non pulsating Low Mass X-Ray Binaries as Very High Energy γ-ray sources, in particular Scorpius X-1; the brightest of these objects in X-rays, and the most likely to be detectable at energies above 250 GeV.

Validation of Global Ionospheric Specification (GIS) Electron Density Measurements During Solar Minimum to Solar Maximum Under Quiet and Disturbed Geomagnetic Conditions

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract Global Ionospheric Specification (GIS) three‐dimensional electron density profiles constructed by assimilating the line‐of‐sight total electron content (TEC) from global navigation satellite system (GNSS) radio occultation (RO) measurements by FORMOSAT‐7/COSMIC‐2 (F7/C2) and ground‐based receiver network from international GNSS service ...
