  2. 6. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Author : Louis Richard; Yuri V. Khotyaintsev; Tomas Karlsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. READ MORE

  4. 7. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Author : Louis Richard; Yuri V. Khotyaintsev; Daniel B. Graham; Andris Vaivads; Emiliya Yordanova; Vassilis Angelopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma jets; Magnetic reconnection; Particle acceleration; Magnetosphere; Magnetospheric Multiscale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : 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. READ MORE

  5. 8. Electron-scale physics in space plasma : Thin boundaries and magnetic reconnection

    Author : Cecilia Norgren; Mats André; Jonathan Eastwood; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 9. Energy Transfer and Conversion in the Magnetosphere-Ionosphere System

    Author : Lisa Rosenqvist; Stephan Buchert; Andris Vaivads; Mike Lockwood; Uppsala universitet; []
    Keywords : Space and plasma physics; solar system; space physics; magnetospheric physics; plasma physics; magnetic storms; substorms; boundary layers; magnetic reconnection; energy conversion; space weather; Rymd- och plasmafysik;

    Abstract : Magnetized planets, such as Earth, are strongly influenced by the solar wind. The Sun is very dynamic, releasing varying amounts of energy, resulting in a fluctuating energy and momentum exchange between the solar wind and planetary magnetospheres. READ MORE
