Observations of the spatial structure of electron precipitation pulsations using an imaging riometer [PDF]
International audienceElectron precipitation can be modulated by geomagnetic pulsation activity. This can be observed as pulsation of cosmic noise absorption as measured by riometers.

Exceptional middle latitude electron precipitation detected by balloon observations: implications for atmospheric composition [PDF]
Energetic particle precipitation leads to ionization in the Earth's atmosphere, initiating the formation of active chemical species which destroy ozone and have the potential to impact atmospheric composition and dynamics down to the troposphere.

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]
Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.

Driver of Energetic Electron Precipitation in the Vicinity of Ganymede
The driver of energetic electron precipitation into Ganymede's atmosphere has been an outstanding open problem. During the Juno flyby of Ganymede on 7 June 2021, Juno observed significant downward‐going electron fluxes inside the bounce loss cone of ...

TEM Study of High-Temperature Precipitation of Delta Phase in Inconel 718 Alloy [PDF]
Inconel 718 is widely used because of its ability to retain strength at up to 650◦C for long periods of time through coherent metastable γ” Ni3Nb precipitation associated with a smaller volume fraction of γ’ Ni3Al precipitates.

The estimation of D-region electron densities from riometer data [PDF]
International audienceAt high latitude the hard electron precipitation associated with auroral activity is a major source of ionization for the D-region, one consequence being the absorption of radio waves.
