Comparison of the characteristic energy of precipitating electrons derived from ground-based and DMSP satellite data [PDF]
, 2005 International audienceEnergy maps are important for ionosphere-magnetosphere coupling studies, because quantitative determination of field-aligned currents requires knowledge of the conductances and their spatial gradients.

Sunyaev Zel’dovich effect in galaxy clusters cavities: Thermal or non-thermal origin? [PDF]
EPJ Web of Conferences, 2022 Several galaxy clusters host X-ray cavities, often filled with relativistic electrons emitting in the radio band. In the cluster MS 0735.6+7421 the cavities have been detected through the Sunyaev Zel’dovich (SZ) effect, but it has not been possible to ...

Resonant scattering of energetic electrons in the plasmasphere by monotonic whistler-mode waves artificially generated by ionospheric modification [PDF]
Annales Geophysicae, 2014 Modulated high-frequency (HF) heating of the ionosphere provides a feasible means of artificially generating extremely low-frequency (ELF)/very low-frequency (VLF) whistler waves, which can leak into the inner magnetosphere and contribute to resonant ...

Observation of electron emission in the nuclear reaction between protons and deuterons
Physics Letters B, 2017 Proton–deuteron fusion reaction has been studied using a proton beam with an energy of 260 keV and a deuterium-implanted graphite target. The reaction product, 3He, usually de-excites by γ-ray emission.

Whispering gallery and surface mode of electrons in lateral and corrugated quantum dots
Materials Research Express, 2020 Quantum dots (QDs) are fundamental elements in the applications related to light–matter interaction, such as solar cells, lasers and sensors. Moreover, some modes of electrons including whispering galley modes (WGMs) and surface modes can be incorporated

Intense laser interaction with micro-bars
Scientific Reports, 2023 Intense laser fields interact very differently with micrometric rough surfaces than with flat objects. The interaction features high laser energy absorption and increased emission of MeV electrons, ions, and of hard x-rays.
