Measurement of MHD Turbulence Properties by Synchrotron Radiation Techniques
Frontiers in Astronomy and Space Sciences, 2022 It is well known that magnetohydrodynamic (MHD) turbulence is ubiquitous in astrophysical environments. The correct understanding of the fundamental properties of MHD turbulence is a pre-requisite for revealing many key astrophysical processes.

Determination of interstellar pickup ion distributions in the solar wind with SOHO and Cluster [PDF]
Annales Geophysicae, 1996 Over the last 10 years, the experimental basis for the study of the local interstellar medium has been substantially enhanced by the direct detection of interstellar pickup ions and of interstellar neutral helium within the heliosphere.
