Space Weather, Volume 23, Issue 4, April 2025.Abstract Space weather events can disrupt satellite navigation, potentially compromising also the accuracy of real‐time flight tracking via Automatic Dependent Surveillance‐Broadcast (ADS‐B). This in turn could limit the situational awareness of pilots and reduce the efficiency of the air traffic management.

Journal of the American Ceramic Society, Volume 108, Issue 4, April 2025.A phase transition from a low‐temperature modification to a high‐temperature modification of Zn‐, (Zn,Mg)‐, and Mg‐Qz‐ss is noticed for SiO2 = 80 and 90 mol%. Mg‐ and (Zn,Mg)‐Qz‐ss display a negative coefficient of thermal expansion (CTE) only when they are in their high‐temperature modification and for SiO2 = 90 mol%. (Zn,Mg)‐Qz‐ss with CTE (30–300°C)

Review of asteroid, meteor, and meteorite‐type links
Meteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

The XOC X-ray Beamline: Probing Colder, Quieter, and Softer [PDF]
arXivFuture strategic X-ray satellite telescopes, such as the probe-class Advanced X-ray Imaging Satellite (AXIS), will require excellent soft energy response in their imaging detectors to enable maximum discovery potential. In order to characterize Charge-Coupled Device (CCD) and Single Electron Sensitive Read Output (SiSeRO) detectors in the soft X-ray ...

DA 362: A Gamma-Ray-emitting Compact Symmetric Object
The Astrophysical JournalThe γ -ray detection from an astrophysical object indicates the presence of an extreme environment where high-energy radiation is produced. With the continuous monitoring of the γ -ray sky by the Fermi Large Area Telescope (LAT) leading to deeper ...
