11. Electron-scale physics in space plasma : Thin boundaries and magnetic reconnection
Sammanfattning : Most of the observable Universe consists of plasma, a kind of ionized gas that interacts with electric and magnetic fields. Large volumes of space are filled with relatively uniform plasmas that convect with the magnetic field. LÄS MER
12. Theory and Applications of Tri-Axial Electromagnetic Field Measurements
Sammanfattning : Polarisation, which was first studied in optics, is a fundamental property of all electromagnetic fields. A convenient way to describe the polarisation of two dimensional electromagnetic fields is given by the Stokes parameters. This thesis deals with different aspects of wave polarisation and electromagnetic field measurements. LÄS MER
13. Electrostatic plasma waves associated with collisionless magnetic reconnection : Spacecraft observations
Sammanfattning : Magnetic reconnection is a fundamental plasma process where changes in magnetic field topology result in explosive energy conversion, plasma mixing, heating, and energization. In geospace, magnetic reconnection couples the Earth’s magnetosphere to the solar wind plasma, enabling plasma transport across the magnetopause. LÄS MER
14. On the Formation and Structure of the Ionosphere of Titan
Sammanfattning : We present results on the ionospheric structure around Titan observed during numerous deep (.... LÄS MER
15. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts
Sammanfattning : High-speed plasma flows (jets) are ubiquitous phenomena in the visible Universe. When the fast plasma flow encounters the ambient plasma at rest, it forms a front where its kinetic energy is dissipated. At the jet front, charged particles gain energy from the electromagnetic fields through heating and acceleration. LÄS MER
